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!

  • PTE Academic

    I learned not to lose the rest of a listening task because I missed one word. I'm genuinely thankful to my tutor for being patient.

    Sebastian Zamora

  • 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

  • AP Exams

    Breaking AP Seminar into smaller pieces worked much better for me. Keeping the sources organized saved a lot of time later. I became much more comfortable asking questions in class.

    Brodie McKenzie

  • IB Diploma

    The IB Diploma format felt unnecessarily confusing at first. Having the lesson move at my pace made the process feel much easier. I left the exam feeling that I had done what I could. Thank you to the tutor who stayed supportive until the end.

    Camila Braga

  • AP Exams

    Over time, AP Physics 2 became one of the most organized parts of my AP Exams preparation. I found a better balance between regular school and exam preparation.

    Dylan Lawrence

  • IB Diploma

    I was close to my target, but my results changed a lot from one test to the next. Thanks to TestPrep for helping me stay on track.

    Krit Thongdee

  • IB Diploma

    When I started preparing for IB Diploma, I wasn't sure what order to study things in. I finally understood what was going wrong in IB World History. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Connecting examples back to the main point made my writing more consistent. Knowing what to study reduced a lot of the stress. The preparation felt calmer than I expected.

    Rina Mori

  • SSAT

    I finally understood what was going wrong in Writing Sample. I learned not to spend the same amount of time on every line of a long text. I found a better balance between regular school and exam preparation.

    Georgia Garland

  • SSAT

    Over time, Middle Level became one of the most organized parts of my SSAT preparation. My confidence improved along with the results.

    Logan Russell

  • SSAT

    We weren't sure whether online lessons would be effective. We were able to follow the mock results regularly.

    Qianyu Du

  • IGCSE / GCSE

    I was taking IGCSE Computer Science at school, but getting used to the exam questions took time. Thank you to my tutor and the TestPrep team.

    Xinyi Gao

  • A-Level

    We noticed that the resources kept changing during independent study. Flexible scheduling helped during a demanding school year. We were pleased with the support we received.

    Dong Xu

  • IB Diploma

    Keeping school units and exam preparation in the same plan worked really well. Over time, IB English B became one of the most organized parts of my IB Diploma preparation. I went into the exam much calmer than I would have before. I was really happy with the lessons.

    Claire Ellison

  • 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

  • AP Exams

    What annoyed me most was losing easy points because I rushed. I could work on exam technique without falling behind in class. Knowing what to study reduced a lot of the stress. I was really happy with the lessons.

    Rohit Chawla

  • ACT

    My written answers became shorter, clearer and easier to follow. Thank you to the tutor who stayed supportive until the end.

    Garrett Driscoll

  • IGCSE / GCSE

    The feedback I received on IGCSE Additional Mathematics was clear and practical. One bad mock no longer made me want to drop the whole plan. Learning when to leave a hard question made a real difference to my timing. I left the exam feeling that I had done what I could. I wasn't trying to learn new topics at the very last minute. A big thank you to my tutor for all the support :)

    Mauricio Cisneros

  • LNAT

    Keeping up with LNAT while school was busy was harder than I expected. I left the exam feeling that I had done what I could.

    Felipe Monteiro

  • LSAT

    Lesson times could fit around school, university or work. I finally understood what was going wrong in Argumentative Writing. I found a better balance between regular school and exam preparation. Thank you to the tutor who stayed supportive until the end.

    Peiyu Sun

  • IGCSE / GCSE

    I chose IGCSE Geography this year and wanted to build a solid base from the beginning. I started noticing the reason for a mistake much faster.

    Jisung Guk

  • AP Exams

    I finally understood what was going wrong in AP Psychology. I wasn't trying to learn new topics at the very last minute.

    Yuki Ishii

  • GRE General

    I knew my target, but I didn't have a realistic routine for GRE General. Thank you to the tutor who stayed supportive until the end.

    Lalita Lertchai

  • LSAT

    Over time, Reading Comprehension became one of the most organized parts of my LSAT preparation. I stopped doing a huge amount one week and nothing the next. I learned not to spend the same amount of time on every line of a long text. After a while, the questions started to feel much more familiar. I left the exam feeling that I had done what I could. I was really happy with the lessons.

    Antonia Quezada

  • UCAT

    The UCAT format felt unnecessarily confusing at first. There was no overnight miracle, but the progress was easy to see.
