IGCSE Chemistry: Extended multiple choice and theory, organised by syllabus chapter so stoichiometry, electrochemistry, organic chemistry and the rest can be revised one at a time.
This book holds Paper 4 only - theory (extended). Every question from every session (May/June, October/November and February/March where Cambridge sets it) and every variant is placed under the syllabus chapter it tests, newest first. Each question keeps its original reference, so you always know where it came from.
IGCSE Chemistry students preparing for Paper 4, private candidates, and teachers who want every question on a topic in one place for homework and class tests.
