Quality exam prep shouldn’t be a barrier

What Bandleep is

Bandleep is a free online practice platform for the IELTS (International English Language Testing System) and CELPIP (Canadian English Language Proficiency Index Program) exams. We provide practice modules for all four language skills — Writing, Reading, Listening, and Speaking — across IELTS Academic, IELTS General Training, and CELPIP General.

The platform is designed for three main groups of test-takers: people applying for Canadian immigration and permanent residency through Express Entry or a Provincial Nominee Programme; students applying to universities and colleges in English-speaking countries; and internationally trained professionals seeking registration with medical, nursing, engineering, or other regulatory bodies in Canada, the UK, or Australia.

How the AI feedback works

Every piece of feedback on Bandleep is generated by a large language model trained to evaluate English writing, speaking, reading, and listening performance using IELTS/CELPIP-style practice criteria, based on public scoring guidance.

For Writing, your essay or letter is checked against the four IELTS band descriptors (Task Achievement/Response, Coherence and Cohesion, Lexical Resource, Grammatical Range and Accuracy) or the three CELPIP criteria (Task Fulfillment, Vocabulary, Sentence Structure). You receive highlighted grammar corrections, vocabulary alternatives, structural suggestions, word count feedback, and an estimated band score or CLB level — all in plain, jargon-free English.

For Speaking, your recorded response is transcribed and then evaluated against the same criteria used by official examiners: Fluency and Coherence, Lexical Resource, Grammatical Range and Accuracy, and Pronunciation for IELTS; or Content, Coherence, Vocabulary, and Listenability for CELPIP. The AI identifies specific patterns — such as over-reliance on simple vocabulary, grammatical errors in complex structures, or unnatural pausing — and explains how to address each one.

For Reading and Listening, after you submit your answers you receive an instant score, a full explanation for every question, and (for Listening) the complete audio transcript with the key words highlighted. These explanations describe not only the correct answer but also why each distractor is wrong — the most effective way to avoid repeating the same mistake.

Accuracy of score estimates

Bandleep provides estimated band scores and CLB levels for practice purposes. These estimates are generated by AI and are not official scores. They are calibrated to be a reliable indicator of your current level, but only British Council, IDP, and Cambridge Assessment English can issue official IELTS scores, and only Paragon Testing Enterprises can issue official CELPIP scores.

We recommend using Bandleep scores to track your progress and identify which skills need the most work, rather than treating them as a guarantee of your result on test day. Consistent practice — combined with attention to the specific feedback provided on each submission — is the most reliable path to improving your actual test score.
