Most students use past papers wrong

Ask a teacher what to do in the last month before exams and almost all of them say past papers. Then watch how a paper actually gets done: at a desk, notes open, no clock, pausing to look things up, checking the answers question by question as you go. Nearly all the value has just been thrown away.

A past paper is not a worksheet. It is the only chance you get to rehearse the actual conditions of the exam, and the conditions are most of what makes exams hard. Knowing the content and being able to produce it in a room, on a clock, with the adrenaline of a paper in front of you are two different skills, and only one of them gets practised at a relaxed desk.

How to run one

• Full paper, full timing, one sitting. Set a timer for the real duration and do not stop it. If your exam opens with reading time, run that too.
• Notes closed. If you cannot answer something, leave a gap and move on, exactly as you would in the exam. The gap is data.
• Do not mark as you go. Finish the whole paper first, or you are practising a stop-start rhythm the exam will not let you have.
• Mark it honestly, against the marking criteria, not against how much you feel you knew. Be harder on yourself than you want to be.
• Then, and only then, go back to the topics that cost you marks.

The part almost everyone skips

The score is the least useful thing a past paper produces. A 58 tells you nothing you can act on. The useful output is the pattern: which question types cost you, whether you ran out of time, whether the marks went on the extended responses or the short ones, whether you lost them on content or on the command word.

A past paper gives you a map, not a score. Most people keep the score and throw away the map.

That pattern tells you what to do next week. Running out of time is a completely different problem from not knowing the content, and it has a different fix. So does losing marks consistently on one command word. You cannot see any of that from a total.

When to start

Earlier than feels reasonable. The common instinct is to wait until you have covered everything, which means the first timed paper you ever sit is a few weeks before the real one, and any structural problem you have surfaces with no time left to fix it. A paper sat early will produce a low score and a very useful map.

If you are running out of past papers, Edapt's Exam Hall generates timed papers on your syllabus with the same clock and reading time, and marks them question by question so you get the map rather than just the number.
