Re-reading feels productive. It rarely is. The reliable finding across decades of learning research is that retrieval (pulling an answer out of your head) beats review (putting information back in).
Retrieval, not review
Every time you answer a question and check it, you strengthen the memory more than re-reading the same material would. Getting it wrong and then seeing the answer is still better than not testing at all.
Space it out
Cramming a topic in one sitting produces a score today and little next week. The same time, split across several days, produces a smaller score today and a much larger one at exam time. Revisit weak topics on a widening schedule: next day, three days, a week, two weeks.
Target the weak spots
You don't need even coverage. You need disproportionate time on the subjects and sub-topics where your accuracy is lowest. That's the whole idea behind the readiness roadmap and, on Diamond, the Revisions loop, which rebuilds practice sessions out of exactly the questions you've been getting wrong.
A workable weekly loop
- Monday–Friday: 20–30 mixed questions a day, plus one timed essay.
- Saturday: review every question you missed that week.
- Sunday: one full essay under exam conditions, graded.
Small, boring, repeated. That's what moves the number.
