I was devastated after my first SAT attempt. The diagnostic test identified my weak points in Reading and Math, and my tutor created a focused plan. In 4 months I went up 240 points and got accepted to UCLA!

  • IMAT

    I finally understood what was going wrong in Logical Reasoning. Knowing the topic wasn't always enough; I had to learn which information the question actually needed. After a while, the questions started to feel much more familiar.

    Alana Donovan

  • IMAT

    I was close to my target, but my results changed a lot from one test to the next. Knowing what to study reduced a lot of the stress.

    Arnav Khanna

  • IMAT

    The IMAT format felt unnecessarily confusing at first. Breaking Chemistry into smaller pieces worked much better for me. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Once I understood the reasons behind the facts, the questions felt less random. There was no overnight miracle, but the progress was easy to see. A big thank you to my tutor for all the support :)

    Minho Kim

  • IMAT

    The IMAT format felt unnecessarily confusing at first. My confidence improved along with the results.

    Tomas Nikolic

  • IMAT

    The lessons started being followed without constant reminders from us. We thank the tutor and the TestPrep team.

    Eleanor Caldwell

  • IMAT

    After my first attempt, I wanted the second round of preparation to feel more organized. We didn't spend extra time on things I already knew. There was no overnight miracle, but the progress was easy to see. A big thank you to my tutor for all the support :)

    Emiliano Ledesma

  • IMAT

    Our son's school schedule was already very busy. A good connection with the tutor developed quite quickly. The tutor's close attention to weaker areas gave us confidence. The tutor supported regular study, not only the lesson content. The lessons started being followed without constant reminders from us. Thank you sincerely to everyone involved.
