Start from evidence, not from the first chapter
The instinct is to start at the beginning of the textbook. That spends the most energy on the topics already secure and arrives at the difficult material when everyone is tired.
Start instead with a recent paper or assessment and sort every question into three piles: confident, shaky, and no idea. The shaky pile is where revision pays best, because the understanding is partly there already.
Weight the plan towards the heavy topics
Not every topic carries the same weight. Number, algebra and proportional reasoning turn up across a whole paper, often inside questions that look like they are about something else.
Check the specification for the exam board and tier being studied, then give the recurring strands more time than the one-off topics. Shape and statistics still matter, but they rarely carry a paper on their own.
Space it out and keep coming back
A topic revised once and never revisited is usually gone within a fortnight. Build a plan that returns to each topic at widening intervals rather than finishing with it in one sitting.
A simple rotation works well. Cover something new, revisit last week's topic briefly, and include one older topic as a warm up. Ten minutes of return visits protects weeks of earlier work.
Use past papers properly
Past papers are a diagnostic tool before they are a rehearsal. Working through one without marking it carefully wastes most of its value.
Mark honestly against the scheme, then write down the reason each mark was lost. Was it the method, an arithmetic slip, a misread question, or running out of time? Those four causes need four different responses.
Once the pattern is visible, go back to the topic rather than straight to another paper. Another paper will simply produce the same errors in a new order.
Make progress visible
Motivation holds up far better when progress can be seen. Keep a short list of the specific things that have moved from shaky to secure.
Revision that never produces a visible win starts to feel pointless, and a pupil who feels it is pointless will quietly stop.
Diagnose first, weight the plan towards recurring topics, space the return visits, and treat every lost mark as information rather than a verdict.
