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

    Everyone recommended different resources and I kept switching between them. Questions from other students often helped me as well. I started noticing the reason for a mistake much faster. It was an intense period, but it was worth it.

    Juliette Guillon

  • ACT

    I was doing questions for ACT Reading on my own but never had a steady routine. I finally understood what was going wrong in ACT Reading. My tutor usually asked me to explain my thinking before stepping in. My written answers became shorter, clearer and easier to follow. There was no overnight miracle, but the progress was easy to see. A big thank you to my tutor for all the support :)

    Femke Hartmann

  • ACT

    Breaking Time Management into smaller pieces worked much better for me. The plan changed with my mock and homework results, so the work never felt random. I can now decide much faster when to move on from a question. Knowing what to study reduced a lot of the stress. My preparation became much more regular and easier to track. Thank you to my tutor and the TestPrep team.

    Qiang Jiang

  • ACT

    I chose ACT Reading this year and wanted to build a solid base from the beginning. It was an intense period, but it was worth it.

    Blake McGrath

  • ACT

    Breaking ACT English into smaller pieces worked much better for me. I found a better balance between regular school and exam preparation.

    Erik Dudek

    Irene Gallardo

    When I started preparing for ACT, I wasn't sure what order to study things in. I'm glad I worked with my tutor through this process.

    Preecha Kanjana

    Breaking Optional Writing into smaller pieces worked much better for me. I went into the exam much calmer than I would have before.

    Natsuki Mori

  • ACT

    At the beginning, we knew very little about the ACT system as parents. The tutor's close attention to weaker areas gave us confidence. Online lessons made it possible to continue without losing time on travel. Communication with the team was straightforward and our questions were answered. Seeing the change in our child made us very happy.

    Fernanda Gomes

  • ACT

    Breaking Optional Writing into smaller pieces worked much better for me. I stopped choosing answers by feel and started looking for evidence in the passage. My confidence improved along with the results.

    Huiying Dai

  • ACT

    As the exam got closer, I wasn't sure what I should actually review. Full-length mocks helped me get used to the real exam pace. I left the exam feeling that I had done what I could. Thanks to everyone who supported me.

    Ren Kaneko

  • ACT

    As the exam got closer, I wasn't sure what I should actually review. I finally understood what was going wrong in ACT Math. The plan changed with my mock and homework results, so the work never felt random. Learning when to leave a hard question made a real difference to my timing. I became much more comfortable asking questions in class. Thank you to my tutor and the TestPrep team.

    Coralie Aubert

  • ACT

    I chose ACT Math this year and wanted to build a solid base from the beginning. Breaking ACT Math into smaller pieces worked much better for me. My tutor made it easy to ask questions from the first lesson. A quick check after each answer helped me catch small mistakes. After a while, the questions started to feel much more familiar. Thanks to TestPrep for helping me stay on track.

    Rina Kimura

    The ACT format felt unnecessarily confusing at first. I became much more comfortable asking questions in class.

    Alper Ozturk

  • ACT

    Our child had a clear goal but no steady study routine. Mistakes became something to work on rather than something to feel bad about. We were able to follow the mock results regularly. A realistic plan for the final weeks reduced stress for the whole family. Communication with the team was straightforward and our questions were answered. We were pleased with the support we received.
