Short diagnostic tests, fill-the-blank paragraphs, and IELTS writing with instant feedback. Every answer comes with the rule explained — from beginner (A1) to IELTS band 9.
Read a short paragraph with numbered blanks and choose the best option for each one.
Answer a real writing task, then receive an estimated IELTS band for Task Response, Coherence & Cohesion, Lexical Resource, and Grammatical Range. Your text is measured with NLTK and spaCy before it is scored, so the feedback cites your actual numbers.
10 multiple-choice questions. The grammar topic stays hidden until you answer.
Every level works across all modes. Choose “All levels” for a mixed diagnostic.
Simple tenses, subject pronouns, basic conjunctions (and, but, because, so), and simple sentence structures.
Connectors (however, therefore, nonetheless), relative and adverb clauses, gerunds, participles, and conditionals.
Subjunctive mood, inversion, causative structures, elliptical clauses, and academic syntax.
Rare academic vocabulary and collocations of the kind used in high-band IELTS writing.
A balanced mix from beginner to IELTS 8–9. A full diagnostic of your grammar.
Filling blanks in a full paragraph shows how sentences connect through pronouns, connectors, and transitions.
You answer by meaning, not by guessing the grammar label. The rule is revealed together with the feedback.
After you submit, each question shows why the correct option fits and why the others do not.
