Hello Cynthia,

Although this is a late reply, I believe it might come in handy for anyone who shares your doubt. Note that the reset feature is currently unavailable for our practice tests on Praxis Test Prep. About the number of practice tests we currently provide, there are two practice tests for each section (math, reading, and writing). So, if you would like to retake those, I am afraid the only route would be to create a new Khan Academy account and start over.

That said, we really appreciate your input and are actively trying to improve our test prep experience. As we grow and expand, we will definitely take this sort of question and feedback into consideration.

Thank you for being part of our community and please let me know if I can be of any further assistance!

All the best,
