Learning English grammar as a school subject — tenses, articles, prepositions, conditionals — needs structure, not another chat app. English Grammar Practice Test turns every grammar topic into a short lesson: a clear rule card, real example sentences, then exercises that check whether the rule actually stuck. Twenty topics run across three levels, beginner to advanced, in 45 bite-sized lessons. Every lesson mixes five different exercise types, every wrong answer comes with an explanation, and every topic tracks its own mastery percentage. All of it is stored on your phone and works with no internet at all. WHAT YOU GET • Past Simple finally sticks: each lesson opens with a plain-English rule card and example sentences before you answer a single question • 20 topics across beginner, intermediate and advanced — from Articles and Prepositions of Time to Conditionals, Passive Voice and Reported Speech • Five exercise types in every lesson — multiple choice, fill in the blank, true or false, sentence reordering and error correction — so you can't pass by memorizing positions • Get one wrong and you immediately see why, with the rule explained right next to your mistake • A Daily Challenge, a timed Quick Quiz, a streak calendar and a weekly chart that show exactly how consistent you have been • Per-topic mastery percentages, accuracy rate and daily lesson goal, so you always know which tense to drill next PERFECT FOR • ESL and EFL students working through grammar level by level, A1 to C1 • Self-learners who want lessons in a sensible order, not random flashcards • Anyone whose speaking is fine but whose tenses fall apart in writing • Learners who study on planes, trains and anywhere without a signal — every lesson is offline WHY NOT JUST USE A GENERAL LANGUAGE APP? Conversation apps teach you phrases, but they rarely explain why it is "have gone" and not "went". This app treats grammar as the subject it is: rule first, examples second, practice third, progress tracked per topic — the way a real grammar course is taught. PRIVATE BY DEFAULT Your progress, streak and quiz results stay on your device. No account, no sign-up, no tracking — and lessons never need an internet connection. FULL ACCESS English Grammar Practice Test requires a purchase: a weekly subscription, a yearly subscription, or a one-time lifetime unlock. Every option opens all 20 topics, all 45 lessons, the Daily Challenge, Quick Quiz and full progress tracking. Pick one topic — Past Simple is a good place to start — and finish its first lesson today.
