The worksheets give twenty problems per chapter, sorted from easy to hard, and the worked answers of every worksheet are collected in Part 2, so a student never meets an answer by accident. The tests give one test per chapter: 8 or 9 questions, 20 marks, 40 or 45 minutes and a calculator allowed, with the mark scheme of every test in Part 2.
The middle school books cover Grade 6, 7 and 8 science, also known as Year 7 to Year 9 or Class 6 to Class 8.
