This app is great! Really good alternative to much more expensive prep courses.

Prep FE is a great app for recent graduates who want to pass the exam. After taking the test once and failing, I bought this app I’m not expecting as much as some of the more expensive prep courses that are available, but I was wrong. The question bank for this app is really similar to the type of logic and thinking that is required for the test. Additionally, the timed exams do a really great job of preparing you on how much time to a lot for each question because that is what becomes the biggest obstacle for most people. Anyone who completed an engineering curriculum within the past year or two but wants to prep a little bit for the exam, this app will do the trick!

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.

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.
