Priorities

How to prioritise subjects for revision

By the Reefwatch editorial team · Updated 7 August 2026 · 5 minute read

The question is not which subject matters forever. It is which subject deserves the next available block. A short weekly ranking makes that decision before you are tired and sitting at your desk.

Quick answer

Rank each subject from 1 to 5 for importance and confidence. Start with subjects that have high importance, low confidence and a close assessment, then review the order every week.

A simple way to start

  1. Rate importance
  2. Rate current confidence
  3. Check the next assessment
  4. Choose a small next action

Define importance clearly

Importance can mean a required grade, a large exam weighting, a topic that unlocks later work or a deadline with consequences. Write the reason beside the score so the number is not arbitrary.

Treat confidence as evidence

Use recent questions, teacher feedback or what you can recall without notes. Feeling familiar with a chapter is not the same as being able to answer a question on it.

Turn the ranking into sessions

A priority is useful only when it changes the calendar. Give the top subject an early block and a second block later in the week. Give lower priorities shorter maintenance work.

Reset after new information

A marked paper, changed deadline or completed topic can move the order. Update the plan rather than continuing with a ranking that no longer reflects reality.

Common questions

Should my weakest subject always come first?

Not automatically. Combine weakness with importance and timing. A weak optional topic months away may be less urgent than a major exam next week.

How often should priorities change?

Review them once a week and whenever a deadline or assessment result changes the evidence.
