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!

  • SSAT

    I was doing questions for Upper Level on my own but never had a steady routine. Breaking Upper Level into smaller pieces worked much better for me. We could make the workload lighter during busy weeks at school or university. I worked on keeping a steady pace instead of rushing the easy questions. There was no overnight miracle, but the progress was easy to see. Thanks to everyone who supported me.

    Emiliano Zuniga

  • SSAT

    Keeping up with SSAT while school was busy was harder than I expected. The plan changed with my mock and homework results, so the work never felt random. A lot of my mistakes came from rushing through the wording of the question. The preparation felt calmer than I expected.

    Noemi Marchetti

  • SSAT

    I wasn't starting from zero, but the same mistakes kept showing up in my mocks. We were realistic about what could be improved in the time available. I went into the exam much calmer than I would have before. It was an intense period, but it was worth it.

    Daan Hoffmann

  • SSAT

    I chose Reading this year and wanted to build a solid base from the beginning. Lesson times could fit around school, university or work. I stopped choosing answers by feel and started looking for evidence in the passage. I started tracking the type of mistake, not just the number of questions I completed. Thanks to TestPrep for helping me stay on track.

    Eylul Polat

  • SSAT

    What annoyed me most was losing easy points because I rushed. Focusing on past papers and mock review worked well near the exam. I became much more comfortable asking questions in class. Thank you to the tutor who stayed supportive until the end.

    Tanvi Joshi

  • SSAT

    Anxiety became more visible as the exam got closer. A good connection with the tutor developed quite quickly. We quickly felt that the tutor was a good match.

    Ludovica Martinelli

  • SSAT

    I finally understood what was going wrong in Reading. My written answers became shorter, clearer and easier to follow. I went into the exam much calmer than I would have before.

    Valentin Mena

  • SSAT

    The feedback I received on Elementary Level was clear and practical. I found a better balance between regular school and exam preparation.

    Asli Yucel

  • SSAT

    At the beginning, we knew very little about the SSAT system as parents. Communication with the team was straightforward and our questions were answered. We were able to follow the mock results regularly. Mock analysis allowed us to follow progress more clearly. The tutor supported regular study, not only the lesson content. We were pleased with the support we received.

    Ethan Townsend

  • SSAT

    The SSAT format felt unnecessarily confusing at first. Over time, Elementary Level became one of the most organized parts of my SSAT preparation. My tutor made it easy to ask questions from the first lesson. Practicing in the real exam format made test day feel much less unfamiliar. There was no overnight miracle, but the progress was easy to see. The preparation felt calmer than I expected.

    Matteo Serra

  • SSAT

    I finally understood what was going wrong in Verbal. By the end of each lesson, I knew what I was supposed to do during the week. My written answers became shorter, clearer and easier to follow. My confidence improved along with the results. I started noticing the reason for a mistake much faster. A big thank you to my tutor for all the support :)

    Camille Tessier

  • SSAT

    At the beginning, we knew very little about the SSAT system as parents. The lessons started being followed without constant reminders from us. Regular mocks built familiarity with the real exam pace. Flexible scheduling helped during a demanding school year. A good connection with the tutor developed quite quickly. Seeing the change in our child made us very happy.
