No one enjoys prepping for the ACT. We know.

We’ve helped students in just about every situation imaginable -- whether they just needed to increase their ACT scores to get into a local college, significantly boost their ACT performance to secure big scholarship dollars and get into an honors college, or score in the 99th percentile for admission to an Ivy-League school.

... need to bump up your score by just a few points OR need to see a huge improvement in results.

… just want the minimum score to get into college OR need a competitive score for scholarships or admission to the most selective universities

… are studying on your own OR are working with a test prep tutor

… are a high school freshman getting a head start on ACT prep or a high school senior who’s running out of time

Before PrepSharp I had like keep every mock test so I can keep track of what test I’ve done and the scores I’ve gotten but now that I have the app it’s made it easier. I don’t have to keep all the tests because PrepSharp lets you log in results of any test. It also keeps track on my progress and shows me if I’m improving or not. It’s made life much easier for my tutor and I. Definitely recommend this app!

Really convenient

PrepSharp makes it super easy to track my progress and communicate with my tutor. I love been able to score my practice tests and log them directly on to the app. It has made the test prep process much more convenient.
