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!

  • ACT

    Discussing why the other choices were wrong helped more than I expected. Thank you to my tutor and the TestPrep team.

    Sydney Brennan

  • ACT

    I was close to my target, but my results changed a lot from one test to the next. It was an intense period, but it was worth it.

    Jack Kerr

  • ACT

    I finally understood what was going wrong in Time Management. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Practicing in the real exam format made test day feel much less unfamiliar. After a while, the questions started to feel much more familiar. I went into the exam much calmer than I would have before. Thank you to my tutor and the TestPrep team.

    Beatrice Palmieri

  • ACT

    I was doing questions for ACT Reading on my own but never had a steady routine. I wasn't trying to learn new topics at the very last minute.

    Yui Abe

  • ACT

    After my first attempt, I wanted the second round of preparation to feel more organized. After a while, the questions started to feel much more familiar.

    Freya Connolly

  • ACT

    After my first attempt, I wanted the second round of preparation to feel more organized. After each test, we looked beyond the score and reviewed the type of each mistake. Seeing several versions of the same topic made unfamiliar questions less stressful. We could make the workload lighter during busy weeks at school or university. The mocks showed where my time was actually being lost. Thank you to my tutor and the TestPrep team.
