The Power IELTS Grammar Book is a 31-chapter reference written specifically for IELTS candidates. It is not a generic ESL textbook — every chapter is paired with IELTS-style example sentences, the kind of academic phrasing examiners reward in Writing Task 2 and Speaking Part 3.
Each chapter ends with a short AI-generated quiz (5–10 items) tied to the IELTS scoring criteria. Wrong answers are pushed into the Ebbinghaus review schedule (1, 3, 7, 14, 30, 60 days) so the rules you miss are reinforced exactly when you are about to forget them. Cross-links connect each grammar topic to the Reading question types and Writing templates where it actually appears.
One of the four official IELTS Writing band descriptors is Grammatical Range and Accuracy, and the same descriptor exists in Speaking. Candidates who plateau at Band 6.0–6.5 almost always have a narrow grammatical range — overuse of present simple, no conditional hedging, and weak relative clauses. This grammar book targets exactly those gaps with examples taken from real IELTS-style topics.
