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!

After trying other programs, TestPrep Istanbul finally worked. The personalized approach to Data Sufficiency and Critical Reasoning made all the difference. Now I'm doing my MBA at Wharton.

  • AP Exams

    I wasn't starting from zero, but the same mistakes kept showing up in my mocks. My tutor made it easy to ask questions from the first lesson. Experiencing the exam format beforehand made test day much less stressful. I became much more careful with graphs, experiments and data-based questions. My preparation became much more regular and easier to track. Thanks to everyone who supported me.

    Jordan Huxley

  • AP Exams

    As the exam got closer, I wasn't sure what I should actually review. Questions from other students often helped me as well. I went into the exam much calmer than I would have before. Thanks to TestPrep for helping me stay on track.

    Martina Grimaldi

  • AP Exams

    Everyone recommended different resources and I kept switching between them. I finally understood what was going wrong in AP Physics 2. Going back to the lesson recordings helped when I forgot a small step. Separating calculation errors from content gaps made revision more useful. My preparation became much more regular and easier to track. A big thank you to my tutor for all the support :)

    Seo Kim

  • IGCSE / GCSE

    The plan was adjusted when school exams became busy. Mistakes became something to work on rather than something to feel bad about. We would recommend the program to students and families in a similar situation.

    Yaren Kartal

  • PTE Academic

    The PTE Academic format felt unnecessarily confusing at first. After enough examples of the same question type, the repeated mistakes decreased. We reduced the memorized phrases so my answers sounded more natural. I stopped doing a huge amount one week and nothing the next. Working across different difficulty levels made new questions feel less surprising. Thank you to my tutor and the TestPrep team.

    Taemin Nam

  • TOEFL iBT

    We reduced the memorized phrases so my answers sounded more natural. It was an intense period, but it was worth it.

    Saki Ota

  • ACT

    I was doing questions for ACT Reading on my own but never had a steady routine. I finally understood what was going wrong in ACT Reading. My tutor usually asked me to explain my thinking before stepping in. My written answers became shorter, clearer and easier to follow. There was no overnight miracle, but the progress was easy to see. A big thank you to my tutor for all the support :)

    Femke Hartmann

  • IB Diploma

    Flexible scheduling helped during a demanding school year. Mistakes became something to work on rather than something to feel bad about. We quickly felt that the tutor was a good match.

    Luisa Willems

  • IGCSE / GCSE

    I wasn't starting from zero, but the same mistakes kept showing up in my mocks. Knowing what to study reduced a lot of the stress.

    Joaquin Paredes

  • SSAT

    Anxiety became more visible as the exam got closer. A good connection with the tutor developed quite quickly. Online lessons made it possible to continue without losing time on travel. The tutor's calm approach helped protect motivation during the intensive period. Joining lessons willingly was one of the clearest signs for us. The overall experience was positive from beginning to end.

    Raul Tavares

  • AP Exams

    Separating calculation errors from content gaps made revision more useful. I'm genuinely thankful to my tutor for being patient.

    Jelena Kristensen

  • IELTS Academic

    Full-length mocks helped me get used to the real exam pace. Over time, Writing Task 2 became one of the most organized parts of my IELTS Academic preparation. I became much more comfortable asking questions in class. Thanks to TestPrep for helping me stay on track.

    Akash Mehta

  • Digital SAT

    Discussing why the other choices were wrong helped more than I expected. It was an intense period, but it was worth it.

    Firat Tekin

  • AP Exams

    Over time, AP Calculus BC became one of the most organized parts of my AP Exams preparation. Near the exam, it was clear what to keep doing and what to stop. I started seeing shorter solutions that were easier to check under time pressure. After a while, the questions started to feel much more familiar. There was no overnight miracle, but the progress was easy to see. Thank you to the tutor who stayed supportive until the end.

    Kendall Langston

  • AP Exams

    I chose AP Physics 1 this year and wanted to build a solid base from the beginning. Questions from other students often helped me as well. I left the exam feeling that I had done what I could. The preparation felt calmer than I expected.

    Alyssa Mendoza

  • PTE Academic

    Balancing PTE Academic preparation with university and work was harder than I expected. I'm glad I worked with my tutor through this process.

    Cody Vickers

  • TOEFL iBT

    The feedback I received on Integrated Tasks was clear and practical. My tutor usually asked me to explain my thinking before stepping in. I learned not to lose the rest of a listening task because I missed one word. I wasn't trying to learn new topics at the very last minute. I went into the exam much calmer than I would have before. A big thank you to my tutor for all the support :)

    Sameer Sharma

  • IB Diploma

    I was taking IB Biology at school, but getting used to the exam questions took time. One bad mock no longer made me want to drop the whole plan. I became much more careful with graphs, experiments and data-based questions. I'm genuinely thankful to my tutor for being patient.

    Matilde Pires

  • IGCSE / GCSE

    Separating calculation errors from content gaps made revision more useful. Thank you to the tutor who stayed supportive until the end.

    Roxane Meunier

  • LNAT

    Breaking Section A MCQ into smaller pieces worked much better for me. Discussing why the other choices were wrong helped more than I expected. My mock results gradually became more consistent.

    Serena Pellegrini

  • ACT

    Breaking Time Management into smaller pieces worked much better for me. The plan changed with my mock and homework results, so the work never felt random. I can now decide much faster when to move on from a question. Knowing what to study reduced a lot of the stress. My preparation became much more regular and easier to track. Thank you to my tutor and the TestPrep team.

    Qiang Jiang

  • IGCSE / GCSE

    After the first attempt, we looked for a calmer plan for the retake. Communication with the team was straightforward and our questions were answered. Online lessons made it possible to continue without losing time on travel. Regular mocks built familiarity with the real exam pace. Joining lessons willingly was one of the clearest signs for us. The overall experience was positive from beginning to end.

    Bailey Rowntree

  • IGCSE / GCSE

    We wanted our child to keep up with the school pace in IGCSE Statistics. We were pleased with the support we received.

    Jiaqi Hu

  • ACT

    I chose ACT Reading this year and wanted to build a solid base from the beginning. It was an intense period, but it was worth it.
