O Level Chemistry Alternative to Practical (ATP)
Cambridge O Level Chemistry's Alternative to Practical paper (Paper 4) tests the same experimental skills as the practical exam — planning, observing, recording and interpreting results — through written questions rather than a lab. Because it draws on experimental technique across the whole syllabus rather than one topic at a time, this is one set of topical papers covering the full ATP paper, taught by Naeem Bukhari, rather than split by syllabus topic the way Theory Questions and MCQs are.
