When you have too much to study and not enough time, prioritise what has the greatest effect on the outcome. Start with imminent assessments, high-value weak topics, foundational knowledge that unlocks several other areas, and recurring errors that continue to cost marks.
Do not spend scarce time polishing what is already secure simply because it feels comfortable. Protect the strong areas with brief maintenance, then direct most active study toward the weaknesses that are both important and realistically repairable in the time available. When necessary, accept that some low-value work will receive less attention.
Use Revision Triage — What Should You Revise Next? for deeper prioritisation, and the Examinations & Assessment Hub when the time pressure is driven by an approaching examination.
