Revision that works
How do I stop running out of time in exams?
Budget marks per minute. Most papers give you roughly a minute per mark - work out your paper's own rate before exam day, set checkpoints (where should I be at half time?), and hold to them. If a question has eaten twice its minutes and you are not moving, mark it, leave it and come back at the end. Finishing the paper earns more than perfecting one question ever does.

The marks-per-minute budget
Every exam paper quietly tells you how to spend your time: divide the minutes by the total marks. On many GCSE and A-level papers that works out somewhere near a minute a mark - check the real numbers for each of your papers, because they vary. From that rate, everything follows: a 2-mark question deserves a couple of minutes, a 6-marker deserves six to eight, and a 20-minute stand at a 3-mark question is a budget catastrophe no brilliance can repay.
Turn the rate into two or three checkpoints before you ever sit the paper - "by half time I should be at roughly half the marks" - and glance at the clock only at those moments. Constant clock-watching burns focus; checkpoints keep you honest without the drip of panic.
Triage rules for the paper itself
A few standing rules take the decisions out of the moment, which is exactly when you are worst at making them:
- Spend the first minute skimming the paper - know where the big-mark questions live before you start.
- Bank the marks you own first. There is no rule that questions must be answered in order.
- Match effort to marks: two lines for two marks, never a page.
- Leave every answer you can - working earns method marks, and a sensible attempt beats a blank on every paper.
- Reserve the last five minutes for returns and checks, and treat that reservation as untouchable.
When to abandon a question (for now)
The single most expensive habit in exams is refusing to let go - pride and sunk cost whispering "one more minute" while three other questions go unanswered. So set the tripwire in advance: if a question has had about double its mark-budget and you are not visibly progressing, put a mark in the margin, take a breath, and move on. This is strategy, not surrender - you are trading a mark you probably cannot reach right now for several you certainly can.
The lovely secret of leaving a question is that it often solves itself in your absence: while you work elsewhere, the background of your mind keeps chewing, and the return visit finds a way in that the siege never did. Even when it does not, you come back calmer, with the easy marks already banked - which is the strongest position to attempt a hard question from.
Train the clock before the clock trains you
Time management is a skill, and skills need rehearsal - the exam hall is the worst possible place for a first attempt. Fold timing into revision gradually: first practise single questions to their mark-budget, then timed sections, then full papers under real conditions, checkpoints and all. If you consistently run out of time in practice, look for the leak: usually it is over-writing on low-mark questions, arithmetic done long-hand, or perfectionism on question one. Each has a fix, and finding it in your bedroom in March is a great deal cheaper than finding it in June.
