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.Chapter map

Tenses — present simple, present continuous, present perfect, past simple, past continuous, past perfect, future forms, and perfect-continuous aspects.

Conditionals — zero, first, second, third, and mixed conditionals with hedging language (would, might, could) that boosts Lexical Resource.

Voice and reporting — active vs. passive, reported speech, causative have/get, and academic nominalisation.

Clause structure — relative clauses (defining, non-defining), noun clauses, adverbial clauses, and reduced relatives.

Word-class deep dives — articles, determiners, quantifiers, modals, gerunds vs. infinitives, comparatives and superlatives.

Advanced syntax — inversion, cleft sentences, parallelism, and complex sentence structures for Band 7+ writing.

How to use it for IELTSEach 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.Why grammar matters for the band scoreOne 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.Power IELTS — power-ielts.com
