TL;DR
Practical crash courses compress essential lab techniques into 2–5 intensive sessions, typically run in June or September. Mock practicals simulate the actual exam - timed, invigilated, with marking and feedback. Most students attend baseline practicals first, then crash courses for revision, then mocks for exam readiness. Crash courses are useful for both school candidates (to supplement school labs) and private candidates (to build skills quickly).
What is a practical crash course?
A practical crash course is a short, intensive programme - typically 2 to 5 sessions - designed to cover the essential lab techniques and exam skills for a specific science subject in a compressed timeframe.
Unlike regular practical programmes that spread sessions across months, crash courses focus on:
- Techniques most likely to appear in the exam
- Common mistakes that cost marks
- Time management under exam conditions
- Exam-specific skills (data presentation, error analysis, planning questions)
Crash courses are not a substitute for sustained practical training. They work best as a revision and consolidation tool for students who already have some lab experience.
What is a practical mock exam?
A mock practical simulates the actual Paper 3 (O-Level) or Paper 4 (A-Level) exam as closely as possible:
| Feature | Mock practical | Actual exam |
| Timing | Full exam duration (e.g., 1 h 50 min for O-Level) | Same |
| Apparatus | Real lab equipment, set up as in the exam | Same |
| Invigilation | Supervised, with exam-like conditions | Same |
