Spot the Mistake — ESL Grammar Practice
What is the Spot the Mistake game?
Spot the Mistake presents a sentence containing one deliberate grammar error. Students must identify the incorrect word or phrase and either choose the correct replacement from four options in MCQ mode, or type it directly in Written mode. Every question includes an explanation of the grammar rule that was broken, making each answer a learning moment.
Questions are drawn from the ESLe College grammar database, targeting the error types most commonly made by students preparing for IGCSE ESL, IB English B and Cambridge B2 First examinations.
How to play
Read the sentence carefully and find the grammar error. In MCQ mode select the correct replacement from four options. In Written mode type the corrected word or phrase directly. After answering, read the explanation to understand the grammar rule before pressing Next.

Why error correction is essential exam practice
The ability to identify and correct grammar errors appears directly in Cambridge B2 First Use of English and in the self-correction skills assessed in IGCSE ESL writing. Students who practise error identification consistently develop a sharper grammatical eye — they learn to catch mistakes in their own writing before submission, which directly improves exam writing scores.
