Case study · Education
AI exam simulators that feel like the real test
Browser-based mock exams for German, nursing English and IELTS, with timed sections, randomised sets and AI-assisted marking for writing and speaking.
The challenge
Where they started
Learners preparing for high-stakes language exams needed realistic practice at any time, not only when a tutor was free to mark papers or run speaking mocks. Paper mocks were slow to mark and could not simulate the computer-delivered experience.

Our approach
How we got there
Mirror the real format
Each simulator follows the official structure, timings and scoring approach of its exam.
Make every attempt different
Question sets are randomised on every login, so learners cannot memorise answers.
Mark with AI
Writing and speaking are marked automatically, with feedback learners can act on.
Connect to learning
Single sign-on from the LMS, with results posted back to the learner's record.
