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!

  • IGCSE / GCSE

    I started seeing shorter solutions that were easier to check under time pressure. Thank you to my tutor and the TestPrep team.

    Samuel Burke

  • LNAT

    Keeping up with LNAT while school was busy was harder than I expected. Breaking Reading Comprehension into smaller pieces worked much better for me. We could make the workload lighter during busy weeks at school or university. My written answers became shorter, clearer and easier to follow. Knowing what to study reduced a lot of the stress. The preparation felt calmer than I expected.

    Damian Ibarra

  • IGCSE / GCSE

    Breaking IGCSE English as a Second Language into smaller pieces worked much better for me. A lot of my mistakes came from rushing through the wording of the question. My preparation became much more regular and easier to track.

    Elisa Fiore

  • AP Exams

    I was taking AP Seminar at school, but getting used to the exam questions took time. Thank you to the tutor who stayed supportive until the end.

    Priscila Campos

  • LNAT

    I was taking Reading Comprehension at school, but getting used to the exam questions took time. We didn't spend extra time on things I already knew. After a while, the questions started to feel much more familiar. Thank you to my tutor and the TestPrep team.

    Marissa Vaughn

  • IMAT

    The IMAT format felt unnecessarily confusing at first. My confidence improved along with the results.

    Tomas Nikolic

  • IGCSE / GCSE

    I chose IGCSE Mathematics this year and wanted to build a solid base from the beginning. Breaking IGCSE Mathematics into smaller pieces worked much better for me. The plan changed with my mock and homework results, so the work never felt random. Seeing several versions of the same topic made unfamiliar questions less stressful. After a while, the questions started to feel much more familiar. I'm genuinely thankful to my tutor for being patient.

    Priscila Correia

  • ACT

    Discussing why the other choices were wrong helped more than I expected. Thank you to my tutor and the TestPrep team.

    Sydney Brennan

  • IB Diploma

    Our child had a clear goal but no steady study routine. The tutor supported regular study, not only the lesson content.

    Tove Kolar

  • AP Exams

    When I started preparing for AP Exams, I wasn't sure what order to study things in. Experiencing the exam format beforehand made test day much less stressful. We focused more on understanding what the problem asked than memorizing formulas. I started tracking the type of mistake, not just the number of questions I completed. Thanks to everyone who supported me.

    Blake Garland

  • LSAT

    My mock scores were inconsistent, so it was hard to judge my actual level. Near the exam, it was clear what to keep doing and what to stop. The group never had more than six students, so it was easy to stay involved. Discussing why the other choices were wrong helped more than I expected. There was no overnight miracle, but the progress was easy to see. A big thank you to my tutor for all the support :)

    Elisa Coppola

  • YÖS / TR-YÖS

    We noticed that the resources kept changing during independent study. A good connection with the tutor developed quite quickly. Preparation looked calmer and more organized closer to the exam. Being able to fit lessons around school made the process easier. We were able to follow the mock results regularly. We were happy with both the teaching and the communication.

    Gonzalo Gallardo

  • AP Exams

    Breaking AP Environmental Science into smaller pieces worked much better for me. Separating calculation errors from content gaps made revision more useful. I left the exam feeling that I had done what I could.

    Kavya Patil

  • GRE General

    I stopped choosing answers by feel and started looking for evidence in the passage. Thank you to the tutor who stayed supportive until the end.

    Franco Salazar

  • IGCSE / GCSE

    Our child had a clear goal but no steady study routine. We thank the tutor and the TestPrep team.

    Jun Guo

  • PTE Academic

    Joining lessons willingly was one of the clearest signs for us. We were pleased with the support we received.

    Miles Harrison

  • ACT

    I was close to my target, but my results changed a lot from one test to the next. It was an intense period, but it was worth it.

    Jack Kerr

  • IGCSE / GCSE

    Our daughter needed regular support with IGCSE English Literature. The tutor's close attention to weaker areas gave us confidence. The overall experience was positive from beginning to end.

    Damla Akbulut

  • PTE Academic

    Breaking Listening into smaller pieces worked much better for me. My confidence improved along with the results.

    Jack Whelan

  • ACT

    I finally understood what was going wrong in Time Management. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Practicing in the real exam format made test day feel much less unfamiliar. After a while, the questions started to feel much more familiar. I went into the exam much calmer than I would have before. Thank you to my tutor and the TestPrep team.

    Beatrice Palmieri

  • LNAT

    When I started preparing for LNAT, I wasn't sure what order to study things in. We were realistic about what could be improved in the time available. My preparation became much more regular and easier to track. I'm genuinely thankful to my tutor for being patient.

    Elise Arnaud

  • TOEFL iBT

    Lesson times could fit around school, university or work. Breaking Integrated Tasks into smaller pieces worked much better for me. My preparation became much more regular and easier to track. Thank you to the tutor who stayed supportive until the end.

    Jonas Schafer

  • AP Exams

    Anxiety became more visible as the exam got closer. Mistakes became something to work on rather than something to feel bad about.

    Rita Cabrera

  • IB Diploma

    When I started preparing for IB Diploma, I wasn't sure what order to study things in. We didn't spend extra time on things I already knew. I wasn't trying to learn new topics at the very last minute. Thank you to my tutor and the TestPrep team.
