This tool is a self-contained practice engine for English as a Second Language learners. It holds a curated bank of grammar items grouped by topic — verb tenses, articles, prepositions and irregular verbs — and each item carries a correct answer, three plausible distractors, and a one-line explanation written in plain English. When you choose a topic, the engine filters the bank, optionally narrows it by your selected difficulty band, then shuffles and draws the number of questions you asked for.
The scoring algorithm is deliberately simple and transparent so you can trust it. Each question is worth one point. The moment you click an option, the engine compares your choice against the stored key: a match marks the option green and adds one to your running total, while a miss marks your choice red and reveals the correct option in green so you learn the right form immediately. The live counter tracks answered and correct separately, and the final percentage is computed as correct ÷ total × 100, rounded to the nearest whole number. A score of 90% or above earns an "excellent" band, 70–89% is "solid", 50–69% is "keep practising", and below 50% suggests reviewing the topic before retrying.
Distractors are not random words — they are common ESL error patterns, such as confusing the past simple with the present perfect, dropping the article before a singular countable noun, or mixing "in", "on" and "at" for time. Seeing the typical mistake next to the correct answer is what makes multiple-choice drilling effective: you train your eye to reject the wrong form. Because every question, key and explanation lives inside this page, the trainer works fully offline and reshuffles instantly, giving you near-unlimited repetition without any account, ads or external requests.
