Exam technique: turning what you know into marks you actually get
Plenty of students lose grades they had already earned in revision. This is a practical walkthrough of timing, command words, mark allocation and the last-ten-minutes check.
There are two separate skills in any exam: knowing the material, and converting that knowledge into marks inside a fixed time under pressure. Revision only trains the first. If your practice papers score lower than your understanding suggests they should, the gap is almost always technique.
Budget by marks, not by question
Work out your minutes-per-mark before you start: total writing time divided by total marks. In a 90-minute, 80-mark paper that is roughly one minute per mark. A six-mark question therefore gets six minutes and not a moment more — overrunning on a question you enjoy is the most common way to lose easy marks at the end of the paper.
Read the command word literally
Describe, explain, evaluate and justify are instructions, not synonyms. Describe wants what happens; explain wants why, with a mechanism; evaluate wants both sides plus a judgement; justify wants a decision defended with evidence. A perfect description scores badly on an explain question, and no amount of extra writing fixes the mismatch.
Let the mark allocation tell you the shape
Marks are a structural hint. Two marks usually means two distinct points, not one point written twice. Six marks with a levels-based mark scheme usually wants a short argument with linked reasoning rather than a list. Count your distinct points against the marks available before you move on.
Show the middle of your working
In quantitative subjects, method marks survive an arithmetic slip only if the method is visible. Write the formula, substitute, then compute. In essay subjects the equivalent is signposting the step of the argument, so a marker can follow your reasoning without reconstructing it.
Keep the last ten minutes for checking
Reserve time to answer three questions: have I answered every part, including the ones on the back page; does each answer address the command word; have I carried units, signs and significant figures through. This pass reliably returns more marks than another paragraph on a question you have already answered.
Practise under exam conditions at least twice
Do two full papers timed, silent and closed-book before the real one. The purpose is not more knowledge, it is calibration: you learn how long six marks actually feels and where your timing breaks. Mark them against the official scheme and treat every lost mark as a technique note, not a knowledge gap, unless you genuinely did not know the content.
Practice tests in StudyPie are built for this loop — timed, graded against your own material, with every missed question available to turn into a flashcard so the content gap and the technique gap get fixed separately.
- Convert the paper into minutes per mark before you write anything.
- Treat command words as instructions; match the answer type exactly.
- Use mark counts to decide how many distinct points to make.
- Always keep ten minutes for a structured checking pass.
