The 80/20 Study Plan: Boost GCSE Maths in 30 Minutes a Day

Short on time? The 80/20 approach focuses on the small set of skills that deliver most exam marks. With just 30 minutes a day, you can make real progress by combining quick practice, immediate feedback, and spaced review.

Why the 80/20 rule works

  • Most marks come from core skills: number fluency, algebra manipulation, ratio & proportion, and geometry basics.
  • Frequent, short practice sessions build automaticity faster than long, infrequent cramming.
  • Immediate feedback prevents errors becoming habits.

The 30-minute daily routine

  1. 5 min — Warm-up fluency: mental arithmetic or times tables to get your brain moving.
  2. 15 min — Focus topic: one subtopic practice set with worked solutions.
  3. 5 min — Error log: write the mistake + the fix in your own words.
  4. 5 min — Spaced review: quickly revisit yesterday’s error log.
