Reading grammar rules is a start, but real fluency comes from applying those rules under pressure. When you complete a quiz, fill a cloze, or unjumble a sentence, your brain has to retrieve the rule and deploy it in context — exactly what happens in real conversation. That process of active retrieval is far more effective than passive reading for long-term retention.
At LexFizz every grammar topic pairs written explanation with immediately playable exercises. You can move from a brief introduction directly into a quiz, a complete-the-sentence challenge, or a cloze dropdown in seconds. All exercises give instant feedback: correct answers reinforce the pattern, incorrect answers show you what went wrong so you can self-correct.
If you are at A1–A2, start with Present Simple and Articles — they appear in virtually every sentence you will ever write or speak. Once those feel comfortable, move to Past Tenses and Present Perfect to handle storytelling and life experience. B1–B2 learners should prioritise Modal Verbs, Conditionals and Passive Voice, all of which are heavily tested in Cambridge exams and IELTS. Advanced learners working toward C1–C2 will benefit most from Phrasal Verbs, Reported Speech and the nuances of Prepositions.
Each topic page gives you a plain-English introduction explaining the grammar point, common errors to avoid, and example sentences. Below the introduction you will find a curated set of interactive exercises for that specific topic. All exercises open instantly in your browser — no download, no account, no cost. Work through them in order for a structured lesson or jump straight to the exercise type you find most challenging.
To go deeper on any topic, each page links to a related blog article with fuller explanations, tables, and IELTS-focused advice. For example, our guides on English verb tenses, modal verbs, conditional sentences, articles, and prepositions each give extended explanations alongside the practice exercises. You can also browse all 30 free exercises or read the LexFizz blog for vocabulary guides, study tips and exam strategies.
