1. Plan and prioritise

Good grades come from two things: understanding how ideas connect, and practising how to express that understanding under exam conditions. Both need planning rather than panic.

  • Keep sessions short and regular. Twenty to thirty minutes most days beats long weekend crams.
  • Mix topics rather than spending hours on one — a bit of bonding, then rates, then energy changes.
  • Work from your exam-board specification and tick off subtopics as you go. It keeps you honest about what's actually left to do.
  • Build in recovery. Sleep, movement and short breaks do more for your memory than "just one more hour".

2. Be active, not passive

Reading and highlighting feel like revision, but they're not. The thing that actually moves your grade is retrieving what you know — pulling it out of your head without the notes in front of you.

  • Use flashcards for the facts you simply have to know — ions, definitions, tests for gases — and review them with spaced repetition (Anki or Quizlet).
  • Explain a topic aloud, or record a 90-second summary of it. If you can't, you've found a gap.
  • Keep a "mistake bank" of questions you got wrong, and re-test yourself on them a few days later.
  • Work through past papers and question packs. This is the single most powerful tool you have.

The cycle is always the same: sit a past paper, mark it against the scheme, find the gaps, relearn them, then repeat. Doing that until command words, mark-scheme phrasing and timing feel familiar is what turns understanding into marks.

3. Exam technique

In Chemistry, marks depend as much on how you answer as on what you know.

  • Underline the command word ("state", "explain", "evaluate") and answer the one in front of you.
  • Use units and significant figures consistently.
  • Show your working — even a wrong final answer can pick up method marks.
  • Practise writing concise, balanced comparisons and full conclusions.
  • Leave a few minutes at the end to check for missing units and unfinished answers.

If technique is your weak point, the fix is volume. Every paper you sit makes the next one feel more familiar, until reading the question correctly stops being the hard part.

4. Manage stress and motivation

Revision isn't only mental effort; it's protecting the energy you bring to each session. A bit of pressure helps you perform, but stress you don't manage just drains you.

  • Try the Pomodoro method: 25 minutes focused, 5 minutes off, with a longer break after four rounds.
  • Look after your body. Hydration, decent food and exercise all feed into recall.
  • Track what improved this week, not just what's still left to learn.
  • Get outside. A walk helps your brain consolidate what you've just revised.

6. Common pitfalls

  • Revising only your favourite topics. Start with the weak areas instead.
  • Ignoring the required practicals — they can account for up to 20% of the marks.
  • Only watching videos. Retention comes from doing questions, not watching someone else do them.
  • Not reading mark schemes. They show you exactly how examiners award marks.

7. A final thought

Small, consistent effort beats heroic last-minute cramming. But if you're reading this the night before a paper, don't panic — focused cramming can still help. Work through past papers, target your weakest topics, and use the mark schemes to see what actually earns marks.

Build recall, practise applying ideas and look after your energy. Do that steadily and you'll usually surprise yourself by exam day.
