- This volume has been designed for students studying physics at examination level at 16+. The contents have been prepared to cover the following syllabuses: GCSE, IGCSE, CXC, and O-level. Each chapter contains core material with additional material specific to the various different syllabuses designated as Further Topics. This enables the individual student or teacher to identify the right mix of pages, according to their own individual syllabus. The illustration style is deliberately international in flavour.
