High School Workbooks for Grades 9-12
Our high school range covers the subjects students most often need extra practice in: Algebra I and II, Geometry, Biology I-III, Chemistry and Zoology. Each workbook follows the same structure: 130 to 200 mini lessons, a step-by-step guide, worked examples and guided practice, so students can work independently at home without a tutor talking them through every problem.
What your high schooler will practise
- Algebra I and Algebra II
- Geometry: angles, triangles, proofs and circles
- Biology I-III: cells, genetics, evolution and physiology
- Chemistry: atoms, bonding, reactions and equilibrium
