PrepEx vs ETS TOEFL TestReady 2026: Official Prep and AI Coaching
Compare official ETS preparation with PrepEx task practice, response feedback and Petra coaching. See the strengths, access limits and reasons to choose either.
Quick answer
ETS is the natural starting point when you want preparation from the test maker. Its resources can support your whole study plan, including learning and practice between full tests.
PrepEx is a strong fit for working on particular tasks, reviewing your own responses and continuing the conversation with Petra. Try that experience if you want coaching alongside regular practice.
What ETS offers now
ETS’s current preparation catalog lists an interactive sample, two free full-length practice tests, an official guide, TOEFL Practice Online and a prep course. The Official TOEFL iBT Prep Course is labeled as updated for 2026 and includes scored Speaking and Writing activities.
Official materials give you direct examples of how ETS presents the test. They are a sound primary choice if you want your study to begin there. There is no reason to reserve them only for a final readiness check.
This page covers ETS’s current public preparation offers alongside the TestReady name readers may know. Access, feedback and device support depend on the product; the linked course currently lists computer support and says it does not support mobile devices.
Where PrepEx adds value
PrepEx combines educator-authored TOEFL practice, full tests and AI feedback on your recorded or written responses. Petra coaching lets you ask follow-up questions and rehearse after reviewing a response.
Choose a task you want to work on, attempt it, inspect the feedback and practice the suggested change. Evaluate whether that coaching helps you understand and improve your own answer.
Try a Listen and Repeat sample or email-writing sample. Our PrepEx review with product evidence shows the experience and its limits. Practice estimates use the 1–6 scale; they are not official TOEFL results or guaranteed predictions.

Choose by what you need next
- Start with ETS if official questions and instruction are your priority. Work through the free material before deciding which paid resource you need.
- Start with PrepEx if you want to choose specific tasks and use response feedback and Petra in the same study routine.
- Get teaching support if you keep encountering the same problem without understanding how to fix it. Neither a practice score nor more attempts alone supplies that explanation.
PrepEx’s free baseline has an access tradeoff
A new free learner unlocks one PrepEx baseline attempt after seven eligible practice attempts. Overall and section practice estimates are included. Detailed answer review and Speaking and Writing feedback on that baseline require Pro.
That prerequisite is an extra step if you want a full mock immediately. See the baseline guide and report screenshots before choosing a plan.
If you combine them, give each a purpose
One possible routine is to study an official example, try an independent task in PrepEx, then ask Petra about a difficulty in your response. Another is to use an ETS course as your main preparation and add selected PrepEx practice when useful. Choose the routine that addresses a real gap; two subscriptions are not automatically better than one.
