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!

  • Digital SAT

    I wasn't starting from zero, but the same mistakes kept showing up in my mocks. I started tracking the type of mistake, not just the number of questions I completed. Lesson times could fit around school, university or work. Sorting mistakes after each mock changed the way I studied. My preparation became much more regular and easier to track. Thank you to my tutor and the TestPrep team.

    Xueying Ma

  • LSAT

    Over time, Argumentative Writing became one of the most organized parts of my LSAT preparation. I wasn't trying to learn new topics at the very last minute.

    Sander Werner

  • LSAT

    I came back to Reading Comprehension after a long break and wasn't sure where to begin. Knowing what to study reduced a lot of the stress.

    Davide Coppola

  • Digital SAT

    I started seeing shorter solutions that were easier to check under time pressure. I'm glad I worked with my tutor through this process.

    Keira Yates

  • AP Exams

    After the first attempt, we looked for a calmer plan for the retake. Preparation looked calmer and more organized closer to the exam. A good connection with the tutor developed quite quickly. Individual lesson time was used around our child's actual needs. Flexible scheduling helped during a demanding school year. Seeing the change in our child made us very happy.

    Gonzalo Correia

  • IGCSE / GCSE

    As the exam got closer, I wasn't sure what I should actually review. Thank you to my tutor and the TestPrep team.

    Marco Basile

  • IGCSE / GCSE

    Online lessons made it possible to continue without losing time on travel. The overall experience was positive from beginning to end.

    Avery Monroe

  • LNAT

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

    Carlotta Bianco

  • YÖS / TR-YÖS

    Anxiety became more visible as the exam got closer. Being able to fit lessons around school made the process easier. Joining lessons willingly was one of the clearest signs for us. Online lessons made it possible to continue without losing time on travel. We would recommend the program to students and families in a similar situation.

    Ozan Kurt

  • AP Exams

    After each test, we looked beyond the score and reviewed the type of each mistake. Breaking AP Psychology into smaller pieces worked much better for me. I became much more comfortable asking questions in class. Thank you to the tutor who stayed supportive until the end.

    Vinicius Miranda

  • AP Exams

    Breaking AP Environmental Science into smaller pieces worked much better for me. Past-paper questions showed me how different topics could appear together. I went into the exam much calmer than I would have before.

    Kiet Saelim

  • IGCSE / GCSE

    We weren't sure whether online lessons would be effective. Thank you sincerely to everyone involved.

    Viviana Acosta

  • AP Exams

    After my first attempt, I wanted the second round of preparation to feel more organized. Lesson times could fit around school, university or work. I went into the exam much calmer than I would have before. Thank you to my tutor and the TestPrep team.

    Fernanda Rezende

  • IGCSE / GCSE

    When I started preparing for IGCSE / GCSE, I wasn't sure what order to study things in. We could make the workload lighter during busy weeks at school or university. After enough examples of the same question type, the repeated mistakes decreased. I became much more careful with graphs, experiments and data-based questions. My confidence improved along with the results. The preparation felt calmer than I expected.

    Isha Trivedi

  • 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 :)

    Rafael Santos

  • IGCSE / GCSE

    The feedback I received on IGCSE Physics was clear and practical. Going back to the lesson recordings helped when I forgot a small step. Separating calculation errors from content gaps made revision more useful. My mock results gradually became more consistent. I left the exam feeling that I had done what I could. A big thank you to my tutor for all the support :)

    Onur Polat

  • IGCSE / GCSE

    Experiencing the exam format beforehand made test day much less stressful. The feedback I received on IGCSE Environmental Management was clear and practical. My mock results gradually became more consistent. I'm genuinely thankful to my tutor for being patient.

    Melis Gokce

  • GMAT Focus

    After my first attempt, I wanted a calmer and more focused plan for the retake. Breaking Data Insights into smaller pieces worked much better for me. One bad mock no longer made me want to drop the whole plan. I started seeing shorter solutions that were easier to check under time pressure. I wasn't trying to learn new topics at the very last minute. Thanks to everyone who supported me.

    Kiara Sanderson

  • UCAT

    I chose Verbal Reasoning this year and wanted to build a solid base from the beginning. Over time, Verbal Reasoning became one of the most organized parts of my UCAT preparation. I stopped doing a huge amount one week and nothing the next. Discussing why the other choices were wrong helped more than I expected. I went into the exam much calmer than I would have before. Thank you to my tutor and the TestPrep team.

    Ruben Cabrera

  • YÖS / TR-YÖS

    Over time, IQ & Logic became one of the most organized parts of my YÖS / TR-YÖS preparation. Seeing several versions of the same topic made unfamiliar questions less stressful. There was no overnight miracle, but the progress was easy to see.

    Madison McAllister

  • 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

  • AP Exams

    We noticed that the resources kept changing during independent study. The lessons started being followed without constant reminders from us. With no more than six students, the tutor had time for everyone. Online lessons made it possible to continue without losing time on travel. Preparation looked calmer and more organized closer to the exam. We thank the tutor and the TestPrep team.

    Zora Babic

  • IGCSE / GCSE

    Our child had a clear goal but no steady study routine. A good connection with the tutor developed quite quickly. We were pleased with the support we received.

    Callum Wylie

  • GMAT Focus

    The feedback I received on Quantitative Reasoning 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. My mock results gradually became more consistent. I found a better balance between regular school and exam preparation. Thank you to the tutor who stayed supportive until the end.
