What TestGlider does well

PrepEx brings educator-authored TOEFL task practice, full practice tests and feedback on your own responses into one place. You can work on a specific task, read or listen to the feedback, and return for another attempt. Petra adds conversational AI coaching for follow-up questions and rehearsal.

Choose the workflow you will use
- Start with TestGlider if you want a test-centered routine and its review and study tools suit you. It can serve as your main practice platform.
- Start with PrepEx if you want to concentrate on selected task types, review your own responses and use Petra for follow-up coaching.
- Consider a teacher if you need someone to explain a persistent difficulty, set priorities or keep you accountable. Neither platform’s AI feedback is the same as personal instruction.
PrepEx’s baseline access is a real tradeoff
One free PrepEx baseline attempt unlocks after seven eligible practice attempts. It includes overall and section practice estimates. Detailed answer review and Speaking and Writing feedback on that baseline require Pro.
The prerequisite gives you time to try the task formats, but it is an extra step if you want a full mock immediately. See the baseline guide and sample report and current free and Pro access.
How to compare them in one study session
- Pick a task you find difficult and try a sample in each service where available.
- Look for feedback that refers to your answer and suggests a change you can make.
- Try another response using that advice. Judge whether you understood what to do, rather than which service gave the higher score.
- Check which parts of the report and practice library your chosen plan includes. Buy a second subscription only if it fills a specific gap.
