Celpip AI vs TOEFLMock

Celpip AI is an independent practice tool for CELPIP-General and CELPIP-General LS that simulates test format and timing. It covers Speaking, Writing, Reading and Listening, each with its own clock. After an answer, it provides an estimated score, a CLB range and four dimension scores; Writing reports also mark sentences with suggested fixes. The site says a full report arrives about five seconds after submission. The maker reports Speaking scores within one band 87% of the time at CLB 3–8 and 43% at CLB 9 and above. For Writing, it reports 95% at CLB 3–8 and provides no upper-band figure. It does not issue official scores and is not affiliated with or endorsed by the named testing and government organizations. The free plan costs nothing and includes three scored sessions for the life of the device, plus free Reading and Listening practice. A listed monthly plan costs $16.99 a month. The service is available on web, iOS and Android.

TOEFLMock provides TOEFL iBT practice aligned with the January 2026 format, with full mock exams and practice for individual sections. Its library is described as 20 full-length exams and 80 section tests. Reading and Listening tests use two-module routing, with performance in the first module determining the next one. Scores use a 1–6 band scale, map to CEFR levels and can also be converted to the legacy 0–120 scale. Speaking and Writing responses receive rubric-based scores, explanations tied to rubric criteria and three suggested improvements. The maker says feedback typically arrives within 30 minutes, though waits can be longer during exam peak weeks. A personal dashboard tracks section weaknesses, band trends, expert feedback and mistakes to review. Paid plans add a 45-lesson course, 1,000 practice questions across 10 task types and 1,500 speaking questions across three tracks. Institute plans include student monitoring, assigned tests and cohort analytics. Practice runs in modern browsers on phones, tablets, Chromebooks, laptops and desktops without app installation. The service is independent and its scores are practice estimates, not official ETS scores.
