Common Entrance assumes a broader syllabus than most Year 8 students have finished, so the gaps tend to be topics simply not yet reached rather than topics misunderstood. Each volume works a group of them through in order, with the mark scheme kept so working can be checked step by step.
A workbook of this shape - 5 topics in curriculum order, 180 questions, mark schemes at the back - is normally printed and sold by a publisher. This one is one of 342 free PDFs on the shelf.
Every chapter opens with a divider page giving its marks and suggested timing, then runs its question pages. The mark schemes for all 5 chapters are grouped at the back, so the book works as homework, as a timed test, or as revision.
Each chapter is one of our worksheet packs, printed here in full. Follow a chapter title to read that pack on its own page, or browse every 13+ Common Entrance pack. Every book on the shelf is a complete printable workbook of up to 120 A4 pages.
In curriculum order, cover to cover. Every volume is its own free PDF - grab the rest of the set below.
The Pack Builder assembles any combination of topics into one PDF, with the answers inline, at the back, or in a separate file.
