O Level Math Study Techniques That Work

Proven O Level Math Study Methods:

The 10-10-10 Method:

Practice 10 similar questions, review 10 mistakes from previous sessions, spend 10 minutes on mental math daily.

Error Analysis Technique:

Keep a detailed error log categorizing mistakes (careless, conceptual, or procedural) and review weekly.

Formula Memory Palace:

Create visual associations and memory aids for formulas. Draw formula sheets from memory regularly.

Backwards Practice Method:

Start with the answer and work backwards to understand the solution process fully.

O Level Math Exam Strategies

Paper 1 (Multiple Choice) Strategy:

  • Aim to complete in 45-50 minutes, leaving time for review
