What the guide holds
Every lesson runs the same way: worked examples paired with a your-turn column, a four-stage practice ladder from fluency to exam-style questions, and full worked solutions for every question at the back of the chapter.
Includes three practice examinations on this chapter, sharing no question between them, each with its own worked solutions. Sit one and keep the other two for revision.
