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

    Our daughter needed regular support with Chemistry. The small group offered peer learning without making it hard to ask questions. The lessons started being followed without constant reminders from us. It was good to see confidence returning over time. We thank the tutor and the TestPrep team.

    Nina Martens

  • IMAT

    Over time, Physics became one of the most organized parts of my IMAT preparation. After a while, the questions started to feel much more familiar.

    Rodrigo Braga

  • IMAT

    When I started preparing for IMAT, I wasn't sure what order to study things in. Lesson times could fit around school, university or work. Once I understood the reasons behind the facts, the questions felt less random. We could make the workload lighter during busy weeks at school or university. We didn't spend extra time on things I already knew. It was an intense period, but it was worth it.

    Felipe Aguirre

  • IMAT

    Having the lesson move at my pace made the process feel much easier. Breaking General Knowledge into smaller pieces worked much better for me. I started noticing the reason for a mistake much faster. Thank you to my tutor and the TestPrep team.

    Rodrigo Galindo

  • IMAT

    I finally understood what was going wrong in Biology. After a while, the questions started to feel much more familiar.

    Ruoxi Yuan

  • IMAT

    Everyone recommended different resources and I kept switching between them. Thank you to my tutor and the TestPrep team.

    Rasmus Prochazka

  • IMAT

    After the first attempt, we looked for a calmer plan for the retake. A good connection with the tutor developed quite quickly. Thank you sincerely to everyone involved.

    Finn Huxley

  • IMAT

    The feedback I received on Physics was clear and practical. I became much more careful with graphs, experiments and data-based questions. My confidence improved along with the results.

    Martina Leone

  • IMAT

    Breaking General Knowledge into smaller pieces worked much better for me. My preparation became much more regular and easier to track.

    Clement Delorme

  • IMAT

    Breaking Chemistry into smaller pieces worked much better for me. I left the exam feeling that I had done what I could.

    Finn Tarrant

  • IMAT

    I finally understood what was going wrong in Logical Reasoning. I started noticing the reason for a mistake much faster.

    Matias Figueroa

  • IMAT

    What annoyed me most was losing easy points because I rushed. Having the lesson move at my pace made the process feel much easier. Seeing several versions of the same topic made unfamiliar questions less stressful. Going back to the lesson recordings helped when I forgot a small step. We didn't spend extra time on things I already knew. I'm glad I worked with my tutor through this process.

    Abbey Elliott

  • IMAT

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

    Sydney Langston

  • IMAT

    I finally understood what was going wrong in Physics. We could make the workload lighter during busy weeks at school or university. I became much more careful with graphs, experiments and data-based questions. I started noticing the reason for a mistake much faster. After a while, the questions started to feel much more familiar. It was an intense period, but it was worth it.

    Nari Yang

  • IMAT

    What annoyed me most was losing easy points because I rushed. Knowing what to study reduced a lot of the stress.

    Everyone recommended different resources and I kept switching between them. It was an intense period, but it was worth it.

    Tao Wu

  • IMAT

    I was close to my target, but my results changed a lot from one test to the next. We could make the workload lighter during busy weeks at school or university. Past-paper questions showed me how different topics could appear together. It was an intense period, but it was worth it.

    James Bennett

  • IMAT

    We wanted our child to keep up with the school pace in Biology. Joining lessons willingly was one of the clearest signs for us.

    Corentin Benoit

  • IMAT

    Working across different difficulty levels made new questions feel less surprising. The feedback I received on Biology was clear and practical. I started noticing the reason for a mistake much faster. Thank you to my tutor and the TestPrep team.

    Misaki Sakamoto

  • IMAT

    I became much more careful with graphs, experiments and data-based questions. I'm glad I worked with my tutor through this process.

    Matilda Goodall

  • IMAT

    Breaking Logical Reasoning into smaller pieces worked much better for me. Separating calculation errors from content gaps made revision more useful. My preparation became much more regular and easier to track.

    Tegan Pemberton

  • IMAT

    I was close to my target, but my results changed a lot from one test to the next. I'm glad I worked with my tutor through this process.
