The Exam Itself
1) Planning your campaign
The first thing to do is read over, carefully, the entire
exam paper. Spend a good ten minutes reading before you write anything. In this
time, work out which questions you are going to answer, which order you are
going to answer them in, and plan your time in the exam: how much time you are
going to spend answering each question. Take careful note of the marking scheme
(see later) when making this plan. Write down the plan on the back sheet of
your answer book - you can always score it out later. It helps you feel in
control, and that helps keep you calm.
Don't be tempted to do a question on subject X just because
it's the subject you know the most about. It might be a real stinker of a
question. Are you sure you can do it? Which parts can you do? How many marks do
you think you could get on the parts of the question you can do? You might find
there is another, much easier question on subject Y, which you might not have
chosen because you found subject Y is harder, or because one part of the
question looks really difficult. Work it out for each part of each question:
which question is likely to get you the most marks? Do that one.
Reading the whole question is also important because many
questions lead you through a problem - the answer to part a) is used in part
b), etc. There might be clues in later parts of the question about what the
examiner is expecting. Make sure you spot them.
As an examiner I am constantly amazed by students who set
out to do questions that they've clearly got not the first clue how to do.
Surely there would be another question on the paper that they could have got a
few marks on at least?
When working out timescales, try and balance the time spend
on a part of the question against the marks you will achieve. If it's a 90
minute exam, and it's marked out of 60, then on average you've got 1.5 minutes
to get each mark. Plan time accordingly. Remember: exam questions are not about
writing down everything you know about a topic - if you do this you'll almost
certainly run out of time. You're trying to get the best mark you can on the
whole paper, not just on the question you happen to be doing at the time.
Obviously, the plan (with timescales) is not a rigid one,
and going a few minutes over on one question is OK – but try and catch it up if
this happens.
2) Do the easiest questions first
There is absolutely no reason to do the questions in the
order they are printed in the exam. I would recommend doing the easiest one(s)
first.
There are two reasons for this. Firstly, getting one question
safely under your belt at the start of an exam is a wonderful boost to
confidence, and can help reduce any feelings of panic that might arise when
looking at the harder questions.
The second reason is that the easiest question is likely to
take less time than the average. That means you’ll be ahead of schedule from
the start – another good confidence boost. It also means that when you get
round to the most difficult question, you are free to spend all the time you
have left on it, without having to drop it half-way through and come back to it
later, if time permits – not a good idea if it can be avoided.
3) Look at the marking schemes – there’s lots of useful
material there.
We have strict marking schemes these days – it’s part of the
drive to be seen to be fair. So, if there are four marks available for the
description of XXX, then the marking scheme will probably have four key points.
Mention them all, and you get the marks. Often, for a question like this, I
will have a list of five or six points, and give one mark for each of them, up
to a maximum of four. One thing you can be (reasonably) certain of: if you
haven’t made four key points, you’ve missed something.
Don’t spend half-an-hour writing a long essay for two marks.
People still do this. It’s a waste of time – better spent on other parts of the
question.
4) One thing to try if you can’t quite get a derivation to
work out (not entirely serious :-)
What you could consider doing in questions of the form
“derive the result shown below” where you’re not sure of all the steps: start
at the top of the page, state the assumptions clearly, and write down the
equations where you’re going to start. About a page and a half later, write the
result, and start working backwards from there. Where the two halves meet,
write “Clearly,”
This gives the examiner a problem. Provided you’ve got the
steps right, and the two halves almost meet up, it’s hard for him to know
whether the missing step is clear to you or not. It might be. You could get the
benefit of the doubt.
Of course, there is some risk here, if you have made a
mistake, and your “clearly” connects two lines that can not possible agree.
While the strict marking schemes we use these days make it hard to penalise
students directly for this sort of thing, it will tend to put the examiner in a
poor frame of mind, and he might start being less generous in marking other
sections of the paper where he has some discretion.
5) Don’t get stuck. Move on.
Avoid writer's block, you haven't got time for it. If you
get stuck on a question, move on. Start doing another one. Staring at a
question you don’t know how to answer is a waste of time, and you’d be amazed
how often, when coming back to a question after half-an-hour, it suddenly
becomes clear.
6) Take a bottle of water in with you. Sip it slowly
throughout.
It’s a good way of remaining calm. Also, you can get through
a lot of nervous sweat during a hard exam. Your body will work better if you
replace it. There is research that suggests this can make a significant
difference to your grades
7) Use common sense.
Even if you don’t have time to go back and find the mistake,
at least write something to indicate that you know something. You might get
some credit for that.
8) Always explain what you are doing.
Too many times I find an exam script where the student has
written an equation with variables in it, and not told me what the variables
represent. If the answer is right, then I can usually figure out what the
variables must be, and the student gets the marks. But if the answer is wrong, then
sometimes it's impossible to work out what they were supposed to be. In this
case the students gets zero for an incomprehensible answer.
9) If you're running out of time.
Suppose you've got time left to do one question, but two
questions left to do. Which one do you choose? The way to maximise your marks
is to do the first half of both of them. You gain marks faster at the start of
a question than at the end.
If you don't have time to write sentences, but you do know
what to do, then just write bullet points. You can get marks for method.
