Mastering Verb Tenses
A clear overview of the main English tenses and when to use each one. Choosing the right tense keeps your meaning precise and your writing natural.
Present Perfect vs Past Simple
These two tenses confuse many learners. The past simple pins an action to a finished time, while the present perfect connects the past to the present.
Using the Passive Voice
The passive voice shifts focus from the doer to the action or its receiver. It is common in academic and formal writing where the process matters more than the person.
Conditionals (Zero to Third)
Conditionals express cause and effect, possibility, and hypothetical situations. Mastering all four types lets you discuss facts, likely outcomes, and imagined scenarios.
Articles: a, an, and the
Articles signal whether a noun is specific or general, known or new. Small as they are, article errors are among the most common issues in IELTS writing.
Prepositions of Time and Place
Prepositions link nouns to the rest of a sentence, showing relationships of time, place, and direction. English prepositions rarely translate directly, so they need memorising.
Relative Clauses
Relative clauses add detail about a noun using who, which, that, whose, where, and when. They let you combine ideas smoothly and avoid short, repetitive sentences.
Conjunctions and Linking Words
Linking words connect ideas to show addition, contrast, cause, and result. Used well, they guide the reader through your argument and improve coherence.
Building Complex Sentences
Complex sentences combine a main clause with one or more dependent clauses. They let you express detailed, nuanced ideas that simple sentences cannot.
Subject-Verb Agreement
A verb must agree in number with its subject. Agreement errors are easy to make when the subject is complex, distant from the verb, or grammatically tricky.
Comparatives and Superlatives
Comparatives compare two things, while superlatives identify the highest or lowest in a group. They are vital for describing trends, data, and opinions in IELTS.
Detecting Common Errors
Proofreading for recurring mistakes is a skill that directly protects your band score. This lesson trains you to spot and fix the errors examiners see most often.
