Key point
In the final week, do timed past papers, identify your three weakest topics and three most common errors, then target those with focused revision. Review definitions and diagrams. Get sleep the night before.
With one week left, you cannot learn everything from scratch. But you can focus on the highest-return activities: practising past papers, strengthening definitions, and reviewing your most common errors. Here is a practical day-by-day approach.
Day 1–2: Past paper triage
Do one full past paper under timed conditions. Mark it honestly against the mark scheme. Identify your three weakest topics: these are your priority for the rest of the week.
Also identify your three most common error types (e.g. Incomplete explanations, wrong command word technique, missing units in calculations). These are often more fixable than knowledge gaps in the final week.
Day 3–4: Targeted revision
For each weak topic, spend 30–45 minutes on:
Re-reading the syllabus statements for that topic
Writing out key definitions and equations from memory
Answering 3–4 past paper questions on that topic
Marking and correcting: the correction is the most important part
Day 5–6: Exam technique and definitions
Spend time on the things that reliably earn marks regardless of which questions appear:
All required definitions (diffusion, osmosis, active transport, etc.)
Command word technique: especially explain and describe
Equations and calculations: magnification, percentage change, rates
The day before the exam, do not cram new material. Review your summary notes lightly, look over corrected past papers, and get a full night of sleep. Sleep consolidates memory more effectively than last-minute studying.
Frequently asked questions
Should I try to learn new topics in the last week?
Focus on strengthening topics you partially know rather than starting from zero on unfamiliar topics. The return on improving a topic from 40% to 80% is higher than taking a topic from 0% to 20%.
How many past papers should I do?
Two to three complete papers, timed, with honest marking. Quality of marking and correction matters more than the number of papers completed.
