Very helpful

Using multiple sources to prepare for FE, I really found PrepFE particularly helpful and easy to use. Great interface, good variety of questions, and support is pretty responsive to any comments that I had regarding particular topics or questions.

Overall, highly recommend this product to aid in your studies.

Helped me pass the FE

Great app for studying for the FE. The questions were very similar to the ones in the actual test. I also really liked the explanations that came in with the problem solutions.

Great app

I’m loving this app so far, but I’d love to see a feature where you can create an exam based off all the questions you answered wrong.
