Revision strategies
Objectives
By the end of this study skills guide, I hope you will be better-able to:
(1) Abandon any unproductive revision
methods you may have suffered from in the past.
(2) Make a sensible decision about when
you will start systematic revision.
(3) Use “revision notes” in
conjunction with question banks, to turn revision into an active process.
(4) Timetable the later stages of your
revision programme sensibly and flexibly.
(5) Organise the time you spend revising
to give you the best possible efficiency.
Can revision be fun?
I guess you’d say “No!”. Well it’s
certainly not fun if its a hard slog, and you have the feeling of getting
nowhere.
How often in the past have you sat for hours at a desk, turning a page every
now and then - with very little “going in”? Has your brain felt
as if it simply couldn’t hold one more fact? Actually, our brains have
enormous storage capacity for information - if only we can use them properly.
When should I start revising?
That’s a question students often ask. If you ask this question, what
you probably want the reply to be is:
“No,
don’t bother starting yet, there’s plenty of time. If you start
too soon you’ll just forget it all again.”
Activity 1
Lets assume you've already started your university course.
If you haven't, imagine yourself a couple of months into the course. Have
you started systematic revision? If you can honestly say 'yes' read on. If
'no', write down your reasons for not yet starting revision, then look at
my response by clicking on 'next' and see if I agree with your reasons.
Reasons why I haven't started revision yet:
As you can guess, ask me when you should start revising, and I’ll give
a very short answer: “Now.” My reasons for this answer include
the following.
• Most people
asking the question already have nagging consciences about not having started.
• If revision
becomes a normal part of your life at an early stage, you avoid having to make
marathon efforts later as exams loom up.
• It’s
much easier to revise things when there isn’t the threat of an impending
exam.
• True, we
forget things we’ve learned, but when we’ve learned something once,
it takes far less time to re-learn it next time, less time still the time after,
and so on.
What’s the best strategy?
We are all different, so there’s no perfect strategy that will suit
everyone. However, there are some ingredients that need to be in any effective
strategy.
• Practice
at answering questions.
• Practice
at recalling things.
• Practice
at assessing your answers.
• Ways of
finding the bits that tend to “slip”.
Have a look at the flowchart below, representing a way of making revision efficient.
Note particularly that bit in the middle: the practice with your question bank.
We explored how to make ‘Question Banks’ in my study skills guide “Making
Learning Tools”. The more time you spend practising answering questions,
the better you get at it. All you have to do in an exam is answer questions.
If you can answer all the little ones in your question bank, you soon become
able to answer bigger ones. Big questions are made up of lots of little ones
anyway.
Effective revision is by definition an active process, very different from
passive reading through your notes or books. When you’re doing real revision,
you’re constantly doing the following:
• formulating
questions
• summarising
• testing
yourself on questions
• checking
how right your answers are
• going back
again to questions which catch you out
More about “revision notes”
If you’ve been using my ideas regarding making summaries of your lectures,
you’re well on the way to making useful revision notes. The same principles
can be used to incorporate into your revision notes summaries of things from
text books, research papers, laboratory or field work, and so on.
The key thing is to drastically reduce the bulk of the material you’re
going to be working with as you revise. This means getting down all the key
ideas, and leaving out all sorts of stuff (however interesting) that you know
you wouldn’t be expected to remember in detail.
Remember the question: “What am I expected to become able to do?”Let’s
explore some characteristics of good revision notes.
• Much shorter
and punchier than original material
• Attractive
to use
• Well laid
out on the paper
• Sufficient
to prompt you towards the answers to most of the questions in your question
bank, without giving the answers directly all the time.
• Portable
enough to carry around with you for use in odd little bits of time, and odd
places!
Does a Revision Timetable help?
Let’s think ahead to the more intensive stages of revision, say during
the final few weeks before your exams come along. Have you made a sort of “diary” of
your revision plans before? Did you actually stick to it?
Activity 2
If you haven't made any plans, which if the following
is closest to your reason for not making such a plan:
- I work better by revising spontaneously, rather than to a schedule
- I couldn't afford the time to make a schedule
- I left it too late to plan any sort of schedule.
How did your reasons for not having a strategy stand up to my comments in
the response to Activity 2? Of course, if you do have such a plan, you can be feeling
rather pleased with yourself.
Let’s take the case that you may have made plans in the past, but not
managed to stick to them. Is this you? It seems to apply to about 9 out of
10 of us.
Try the next activity now: be honest!
Activity 3
If you haven't managed to stick to your revision plans
in the past, type the things that stopped you.
Flexible Plans
Let’s suppose for sake of argument, that you’ve
got five subjects, with five exams coming up in a few weeks time. Suppose
we already know the dates and times of the five exams.
Let’s simply call the subjects A, B, C, D and E.
Each of these subjects will contain a number of different “bits” or
topics. Again, for sake of argument, let’s suppose that on average each
subject has half-a-dozen main “bits”: call them A1, A2, ...A6;
B1 .. B6, and so on.
Look now at the “calendar” of the last few weeks shown in Figure
1. The exams are already marked in. Now I want you to imagine that you’ve
already done quite a bit of revision, and you’re about to plan the more
intensive phase, leading up to your exams. So really, in this plan, it’s “polishing”,
rather than starting from scratch. Try the activity below, then compare your
answer to my response.
Activity 4
In the calendar of Figure 1 below fill in letters such
as A1-4, B2, E6 and so on, to plan a sensible way of using the last few weeks
for systematic, intensive, 'polishing' revision. Don't worry yet about exactly
how this intensive revision can be done, we'll soon go on to explore this
in detail.
What about the more intensive stages?
We’ve now explored “global” planning of the last few weeks
before exams. Let’s now go on to look at how best to use this time -
let’s look at the minute-by-minute processes you can use.
As exams loom up, you probably feel you should be working a lot. However, it’s
not how long you work that counts, it’s how efficient your work is that
matters.
What are the “enemies” ?
• turning
the pages with nothing happening!
• boredom
• resentment
that you’re not doing something else
• fatigue
• panic!
Next we’ll explore ways of removing these “enemies”.
First though, remembering that real revision is an active process, how long
can you do it for?
Activity 5
How long can you sit at your desk or table, and actively revise? In other words, how long can you sustain the active process of revision before you need a break? Choose the option that fits you best, on average.
(a) 15 minutes or less
(b) 30 minutes or so
(c) 1 hour
(d) 2 hours
(e) 3 hours or more
Dangers of the “hard slog”
Suppose it were possible to plug some electrodes into
your brain as you were revising. Imagine the electrodes could be connected
to a computer which measured how much of what you revised you retained as
you sat working. First, let’s
see what might happen if you sat at your desk or table, working as continuously
as you could for a spell of some hours.
Activity 6
Draw a line to show how you think your retention may vary as a function of time
you sit trying to revise.

“Breaks and changes” method
Imagine, now, that your revision strategy had the following features built
into it:
• Shortish
spells of work of no more than about three-quarters of an hour - many spells
being less than this maximum.
• Distinct “breaks” of
a quarter of an hour or more between each spell of revision. These breaks could
be used for a cup of coffee, a short TV programme, a walk around, a meal, anything
where you get away from the work for a short period (as long as you remember
to come back to it, of course!)
• Variety.
When you come back after a break, you press on revising a different topic than
the one you were revising in the previous spell.
• Rapid recaps:
for the first minutes or so of your second spell of revision, you sit, perhaps
eyes closed, and gently let the ideas you revised during your first spell filter
back through your mind. Then, press on with revising the new topic.
If we were to draw a graph of retention against time, it could look something
like Figure 3 below.

How do breaks and changes help?
The last figure looks a bit complex! However, each time
you return to something fresh, your retention will tend to go back up again. “A change is as
good as a rest”. Also, you’ll not get so tired, because you’re
having breaks in between spells of work. Furthermore, you’re less likely
to get bored or fed-up, because even when revising your least-favourite topic, “the
end is in sight” - you’ll soon be moving on to something else.
A lot of short spells of revision adds up to more than a few long ones. Are
you now wondering “will not this chopping and changing of topics leave
my brain in a whirl?” Well, I suggest that our brains’ natural
way of taking in information is in little bits and pieces, rather than “solid
lumps”.
Think about the following analogy. Think of some television serial you’ve
enjoyed. Remember the sort of serial where this week’s episode ends at
some highly dramatic point? You’re dying to know what happens next, but
you’ve got to wait till next week’s episode. Next week, when you
see the opening seconds of the programme, you very quickly recall the dramatic
circumstances in which this week’s story ended. The “sudden stop” left
loose ends in your mind; unresolved questions floating around, and so on. These
remained in your subconscious, ready to surface again as soon as the serial
resumed. It’s very similar if you stop revising right in the middle of
something. When next you pick up the threads, your mind quickly latches on,
because of those loose ends that have been left floating around. It’s
better in fact, than waiting for a “tidy” stopping place: if all
the loose ends are resolved before you leave your topic, your mind does not
hold on to the ideas in the same way.
Should you learn everything?
If you’re just starting your university course, you’re probably
optimistic, and think that given time, you’ll manage to learn all of
the various subjects you need to. However, time goes very quickly when exams
are getting closer, and you may find that you haven’t quite time to learn
all your topics. You may know that your exams give you some choice, maybe any
five questions from eight, or some similar choice.
Activity 7
(a) What's the advantage of trying to cover the whole of the syllabus?
(b) What can sometimes be advantageous of learning most but not all of your
syllabus? (Obviously, you may have to make a compromise! Be careful to minimise
any dangers involved.)
Was your analysis of the pros and cons of learning all or part of your syllabus
similar to mine? In practice, the decision you’ll make is often guided
by the topics themselves. Now and then, there’ll be a small topic you
really don’t like at all. If you are quite sure that:
• this topic
isn’t particularly important, and
• that only
one question is likely to involve it, and
• that it
would take you a lot of time and effort to master the topic,
then you may be justified in skipping it, and spending the time on learning
other things.
Using fellow-students to help you
Almost everything I’ve said in this section has been to do with work
you do “privately”. Revision has usually been regarded as “private”.
At school, many pupils are afraid to admit that they’ve been doing a
lot of revision - that would make them unpopular.
However, everything I’ve said can easily be extended to “sociable” revision,
working with university friends. I’d like you to glance back through
the section, before going on to your action plan, and think how you can use
other people in many of the stages we’ve explored. Include help from
other people in your action plan.
Action plan
Write below your personal plans regarding the various
facets of revision we’ve
discussed. Then if you’re brave enough, get someone else to look at your
plan. Choose someone who will help to keep you to it!

Things I’m going to try regarding “breaks and changes”

What I’m going to avoid in future!
Postscript
I’d like you to look again at the objectives we
set out with at the start of this section:
(1) Abandon any unproductive revision methods
you may have suffered from in the past.
(2) Make a sensible decision about when
you will start systematic revision.
(3) Use “revision notes” in
conjunction with question banks, to turn revision into an active process.
(4) Timetable the later stages of your
revision programme sensibly and flexibly.
(5) Organise the time you spend revising
to give you the best possible efficiency.
I hope by now you’re feeling much more in control of your revision. It’s
all quite logical really, revision is “rehearsal” for the tasks
such as exams that face you. it is something that you can systematically tackle,
a bit at a time. It isn’t something which will take care of itself. It
doesn’t happen overnight as if by magic.
I hope also, that you now can go about the task of revising, in a way that
is “kinder” to
yourself than the old-fashioned hard slog. Learning should be fun, and it certainly
is more enjoyable when you have the feeling that, for every bit of time you spend,
you’re getting tangible results. You aren’t looking for massive sudden
increases in your abilities or skills, simply a systematic, well-organised, gradual
build-up, till you’re well able to meet any standards expected of you.
Responses to Activities
Activity 1
Have I spotted your reasons? Look at the reasons you could have chosen (maybe
you thought of even more)
• If I learn
things too early, I’ll forget them again.
• I’m
too busy just now writing essays.
• I’ve
got homework that has to be handed in.
• I’ve
got practical work I have to write up.
• I never
revise this early, I’m better nearer the exams.
• No-one else
is revising yet, why should l?
Were any of these your reasons too? Excuses, of course! If you’ve got
exams coming along, more depends on how well you revise, than on any other
thing. Well as you might do in essay, homework, practical write-ups, and any
other work, you still need to have invested plenty of time and energy in really
getting to grips with your subject. “Getting to grips” takes time,
it can’t be rushed, and you can’t do a lot of it at once anyway.
So the earlier you start, the better your chances.
If you had some reasons that were not on my list, check for yourself that they
were not excuses.
Activity 2
If you selected reasons for not making any revision plans, check my response
to them below.
• “I
work better by revising spontaneously, rather than to a schedule” .
A good reason in its way. However, it is possible to make plans which still
allow you quite a bit of flexibility. More about this soon.
• “I
couldn’t afford the time to make a schedule”:
I think this is an excuse rather than a reason. It doesn’t take long
to make a plan, as you’ll soon find out. To repeat the old adage: “To
fail to plan is to plan to fail”.
• “I
left it too late to plan any sort of schedule”:
Well, there’s no answer to that! I hope I’ve already convinced
you to start much earlier, and that you’ll have plenty of time to plan
your revision from now on.
Activity 3
• I got behind
in my schedule, and gave up.
• Some things
took longer than I had planned, and threw my timetable out.
• I got “hostile” and
fed-up of sticking to my plans.
• I simply
had to get away from it all for a while, and this meant my timetable was redundant.
If any of these were your reasons, it’s not that you can’t stick
to a plan, it’s because the sort of plan you made was not easy to keep
to. We’ll explore how to make plans which are more flexible and accommodating.
Activity 4
Compare your “calendar” with mine below - don’t worry if
they don’t look anything like each other! Then look at my notes below
Figure 4, and think about whether you calendar could be made more useful by
incorporating any of the suggestions there. (Of course, you may well have incorporated
the lot already, in which case, congratulations!)

Here are the “ingredients” in my calendar, which are intended
to make it as flexible and useful as possible.
• Planned
time off
None of us can work all the time! To take this into account, I’ve planned
the odd day or half day as time off. Now suppose you’re doing a lot of
work on three consecutive days, but you know that the next day is a planned
break. You’ll be better-able to soldier on though your planned work,
looking forward to the planned relaxation.
During your days-off, you’ll have an easy conscience. Much easier than
if you’d slunk away from your work when you got too fed up to do any
more. You’ll be able to say to yourself: “this time off is part
of my plans; I’m going to relax and enjoy it”.
• “Recap” times
Most of my calendar was filled with subject-topic letters and numbers. But
every now and then, I simply put “Recap”. This gives even more
flexibility. In a rigid plan, when something takes longer than you planned,
the whole plan may be thrown out of gear, then you start to distrust the plan,
and probably abandon it altogether. The “recap” slots give you
that extra flexibility . When something is taking longer than you thought it
would, you can save it for a “Recap” slot. When things are going
close to plan, you can use the “Recap” slots for having another
look at things you recently revised, - giving them another polish.
• Plenty of
variety
You’ll notice that on most days, I’ve put several different topics
or subjects. I did this rather than (for example) working all the way through
subject A, then B, and so on. They say “a change is as good as a rest”.
Variety helps you not to be bored and depressed. Suppose at the moment you
are struggling with a really tough element, say C5, at least you’ll know
the struggle will only be for a short time. You’ll then go on to something
different and easier, going back again for another bash at C5 later in your
plans.
• Logical
structures
My calendar was in fact constructed backwards! I started from the exam dates,
and worked back. This is particularly useful where you have two exams close
together. The danger is that you do plenty of work for the first of the two,
but leave too much of the work for the second, hoping to fit it all in to the
limited time between the two exams. Planning backwards, you can make sure that
the second exam’s revision gets timetabled in during the days leading
up to the first of the two exams as well. This can help saving you from passsing
the first exam with flying colours, but failing the second one. Much better
to get reasonable passes in both of the two exams.
Activity 5
(a) “15 minutes of less” -
not too much less I hope! Well, you’re honest! In fact, this can be made
to work well, if you manage to come back and do more and more of your short
spells of revision, and keep the breaks between spells within reason.
(b) “ 30 minutes of so”: this
could, in fact, be ideal. If you work for much longer, you may start “drifting
away” mentally, and not getting true value for the time you’re
sitting. (If you mentally drift away, you may as well physically drift away
and have a rest or a change!) Obviously, you’ll need to build in a fair
number of slots of 30 minutes or so, to get all the revision done you need.
(c) “1 hour”: I wish
I could concentrate for a solid hour! Remember, we’re talking about active
things, such as:
• formulating
questions
• summarising
• testing
yourself on your questions
• checking
how right your answers are
• going back
again to questions which catch you out
Now it’s easy enough to sit and write an essay for a solid hour, but
can you do the active things above for that long? If you can, great. But beware
of mental fatigue, and “drifting off”.
(d) “2 hours”: you honestly
say you can:
• formulate
questions
• summarise
• test yourself
on your questions
• check how
right your answers are
• go back
again to questions which catch you out
for two hours at a stretch? I think you’d either get very tired, or you’d
soon rebel against such a regime.
(e) “3 hours or more”: I think
you may be kidding yourself!
Look at my responses to the options above, then decide for yourself. Obviously,
if you can work for such long spells, and maintain active, efficient revision,
keep it up - and let me know how you do it!
Activity 6
I think my retention would start fairly high, but soon start to drop. Eventually,
I would get into a state where I was still turning the page every now and
then, but not much was “going in”. Have you too felt this happen?

Quite a bit of the time would be wasted. If nothing much is being retained,
we may as well be doing something else!
There is a tiny “peak” right at the end of the graph. That’s
where I get so fed up, I throw down the books and escape - I tend to remember
the last little thing I read before giving up! Obviously, the area under this
peak is far too insignificant to make it worthwhile staying on till this “bitter
end”.
Activity 7
(a) I’d say that the advantage of
trying to learn all of your syllabus is that you’ve got the greatest
possible choice in the questions you will be able to tackle in your exams.
Also, of course, it means that you’re going to be more knowledgeable
than if you only learned parts of your syllabus. If time allows you to learn
the lot: great!
(b) Suppose that you know that you’ve
got a choice in an exam, of any five questions out of eight. Let’s take
two extreme cases.
Sheila learns
the whole syllabus. She learns it on average 6755 perfect. What would you expect
her exam score to be, all things being equal? Yes. 6755
Amanda chooses
to spend all her time learning five-eighths of the syllabus. She learns this
825; perfectly. She can only tackle five of the eight questions in the exam,
but she’s lucky, and has learned what she needs for them. Her exam score?
Yes, 825; that’s with luck, of course. If she had trouble with one of
the questions she’d prepared for, her score could be a lot less, there
being no room for manoeuvre left.
