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

    Full-length mocks helped me get used to the real exam pace. I finally understood what was going wrong in Biology. My mock results gradually became more consistent. I'm genuinely thankful to my tutor for being patient.

    Anais Lambert

  • IMAT

    I was close to my target, but my results changed a lot from one test to the next. During the intensive review, we returned to real gaps instead of restarting everything. I learned to make a short plan before starting a long response. We could make the workload lighter during busy weeks at school or university. We were realistic about what could be improved in the time available. Thanks to everyone who supported me.

    Ceren Gurbuz

  • IMAT

    Keeping up with IMAT while school was busy was harder than I expected. Even in a group lesson, the tutor knew where each of us stood. Knowing what to study reduced a lot of the stress. Thanks to everyone who supported me.

    Niran Thongdee

  • IMAT

    The feedback I received on Logical Reasoning was clear and practical. I started tracking the type of mistake, not just the number of questions I completed. Once I understood the reasons behind the facts, the questions felt less random. I became much more comfortable asking questions in class. My mock results gradually became more consistent. I'm genuinely thankful to my tutor for being patient.

    Zuzana Babic

  • IMAT

    Anxiety became more visible as the exam got closer. Communication with the team was straightforward and our questions were answered. Being able to fit lessons around school made the process easier. The lessons started being followed without constant reminders from us. Seeing the change in our child made us very happy.

    Haruto Nakajima

  • IMAT

    I finally understood what was going wrong in Physics. I went into the exam much calmer than I would have before.

    Rowan Tierney

  • IMAT

    Over time, General Knowledge became one of the most organized parts of my IMAT preparation. My tutor made it easy to ask questions from the first lesson. Source questions became easier once I noticed how small details affected the mark. I became much more comfortable asking questions in class. Knowing what to study reduced a lot of the stress. Thank you to my tutor and the TestPrep team.

    Natalia Carranza

  • IMAT

    I chose Mathematics this year and wanted to build a solid base from the beginning. We didn't spend extra time on things I already knew. Learning when to leave a hard question made a real difference to my timing. One bad mock no longer made me want to drop the whole plan. I'm glad I worked with my tutor through this process.

    Jingyi Sun

  • IMAT

    Our son's school schedule was already very busy. Being able to fit lessons around school made the process easier. Thank you sincerely to everyone involved.

    Naina Das

  • IMAT

    The feedback I received on Logical Reasoning was clear and practical. Once I understood the reasons behind the facts, the questions felt less random. I left the exam feeling that I had done what I could.

    Julian Saavedra

  • IMAT

    Anxiety became more visible as the exam got closer. Flexible scheduling helped during a demanding school year. We would recommend the program to students and families in a similar situation.

    Marit Jansen

  • IMAT

    I was close to my target, but my results changed a lot from one test to the next. I finally understood what was going wrong in Mathematics. One bad mock no longer made me want to drop the whole plan. We focused more on understanding what the problem asked than memorizing formulas. My mock results gradually became more consistent. Thanks to everyone who supported me.

    Enrico Piras

  • IMAT

    I learned to make a short plan before starting a long response. I'm genuinely thankful to my tutor for being patient.

    Tessa Whitaker

    Alessia Serra

  • IMAT

    Our child wasn't sure how to organize the preparation for IMAT. It was good to see confidence returning over time.

    Kazuki Ota

  • IMAT

    When I started preparing for IMAT, I wasn't sure what order to study things in. Having the lesson move at my pace made the process feel much easier. I learned to make a short plan before starting a long response. My tutor usually asked me to explain my thinking before stepping in. I'm glad I worked with my tutor through this process.

    Ana Oliveira

  • IMAT

    Lesson times could fit around school, university or work. Over time, General Knowledge became one of the most organized parts of my IMAT preparation. I left the exam feeling that I had done what I could. Thank you to the tutor who stayed supportive until the end.

    Yuna Tanaka

  • IMAT

    I finally understood what was going wrong in Logical Reasoning. Separating calculation errors from content gaps made revision more useful. After a while, the questions started to feel much more familiar.

    Claudia Branco

  • IMAT

    I chose Chemistry this year and wanted to build a solid base from the beginning. The feedback I received on Chemistry was clear and practical. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. 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. It was an intense period, but it was worth it.

    Kenta Hasegawa

  • IMAT

    We wanted our child to keep up with the school pace in Biology. We would recommend the program to students and families in a similar situation.

    Ceren Polat

  • IMAT

    I wasn't starting from zero, but the same mistakes kept showing up in my mocks. After enough examples of the same question type, the repeated mistakes decreased. I went into the exam much calmer than I would have before. Thanks to TestPrep for helping me stay on track.

    Anong Kanjana

  • IMAT

    We noticed that the resources kept changing during independent study. Mistakes became something to work on rather than something to feel bad about. The lessons started being followed without constant reminders from us. Being able to fit lessons around school made the process easier. Preparation looked calmer and more organized closer to the exam. Thank you sincerely to everyone involved.

    Victor Macedo

  • IMAT

    It was good to see confidence returning over time. Mistakes became something to work on rather than something to feel bad about. We quickly felt that the tutor was a good match.

    Keeping up with IMAT while school was busy was harder than I expected. It was an intense period, but it was worth it.
