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

    We didn't spend extra time on things I already knew. I finally understood what was going wrong in AP Physics 1. I went into the exam much calmer than I would have before. It was an intense period, but it was worth it.

    Caitlin Teague

  • SSAT

    I was doing questions for Middle Level on my own but never had a steady routine. The feedback I received on Middle Level was clear and practical. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. I can now decide much faster when to move on from a question. I went into the exam much calmer than I would have before. Thanks to TestPrep for helping me stay on track.

    Tegan Whelan

  • ACT

    I was taking ACT Math at school, but getting used to the exam questions took time. I stopped doing a huge amount one week and nothing the next. We focused more on understanding what the problem asked than memorizing formulas. I'm glad I worked with my tutor through this process.

    Priscila Nunes

  • PTE Academic

    I knew my target, but I didn't have a realistic routine for PTE Academic. Having the lesson move at my pace made the process feel much easier. It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. My tutor usually asked me to explain my thinking before stepping in. Lesson times could fit around school, university or work. I'm glad I worked with my tutor through this process.

    Ishita Banerjee

  • IB Diploma

    I chose Theory of Knowledge (TOK) this year and wanted to build a solid base from the beginning. I never felt awkward asking the same thing again. The feedback helped me improve my own work without writing it for me. Thank you to my tutor and the TestPrep team.

    Flynn Donovan

  • IELTS Academic

    The feedback I received on Speaking was clear and practical. It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. After a while, the questions started to feel much more familiar.

    Sungmin Yang

  • IMAT

    What annoyed me most was losing easy points because I rushed. Questions from other students often helped me as well. I learned to make a short plan before starting a long response. The plan changed with my mock and homework results, so the work never felt random. Even in a group lesson, the tutor knew where each of us stood. It was an intense period, but it was worth it.

    Yerin Ahn

  • IELTS Academic

    After the first attempt, we looked for a calmer plan for the retake. A good connection with the tutor developed quite quickly. It was good to see confidence returning over time. The tutor's close attention to weaker areas gave us confidence. Mistakes became something to work on rather than something to feel bad about. The overall experience was positive from beginning to end.

    Adrian Pires

  • A-Level

    I was taking A-Level Art and Design at school, but getting used to the exam questions took time. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Focusing on past papers and mock review worked well near the exam. Reviewing my work against the criteria changed the way I edited it. My mock results gradually became more consistent. A big thank you to my tutor for all the support :)

    Ece Bilgin

  • UCAT

    When I started preparing for UCAT, I wasn't sure what order to study things in. I became much more comfortable asking questions in class.

    Tomas Cuellar

  • IGCSE / GCSE

    I was taking IGCSE Geography at school, but getting used to the exam questions took time. One bad mock no longer made me want to drop the whole plan. Source questions became easier once I noticed how small details affected the mark. Thanks to TestPrep for helping me stay on track.

    Ignacio Tapia

  • AP Exams

    What annoyed me most was losing easy points because I rushed. I stopped doing a huge amount one week and nothing the next. We didn't spend extra time on things I already knew. I learned to separate the information needed for a decision from the extra detail. I started noticing the reason for a mistake much faster. Thank you to the tutor who stayed supportive until the end.

    Tiago Rojas

  • IB Diploma

    Everyone recommended different resources and I kept switching between them. I started tracking the type of mistake, not just the number of questions I completed. The class felt relaxed enough to ask questions without overthinking it. I stopped listing facts in essays and started building an actual argument. After a while, the questions started to feel much more familiar. I was really happy with the lessons.

    Marcos Barros

  • PTE Academic

    We didn't spend extra time on things I already knew. Breaking Reading into smaller pieces worked much better for me. There was no overnight miracle, but the progress was easy to see. I'm glad I worked with my tutor through this process.

    Mariel Tolentino

  • IB Diploma

    Over time, IB Psychology became one of the most organized parts of my IB Diploma preparation. I learned to make a short plan before starting a long response. I became much more comfortable asking questions in class.

    Efe Keskin

  • LSAT

    Over time, timed section practice became one of the most organized parts of my LSAT preparation. My written answers became shorter, clearer and easier to follow. After a while, the questions started to feel much more familiar.

    Meera Trivedi

  • SSAT

    The SSAT format felt unnecessarily confusing at first. One bad mock no longer made me want to drop the whole plan. Having the lesson move at my pace made the process feel much easier. Seeing several versions of the same topic made unfamiliar questions less stressful. My mock results gradually became more consistent. Thank you to my tutor and the TestPrep team.

    Denise Cruz

  • AP Exams

    What annoyed me most was losing easy points because I rushed. The feedback I received on AP World History was clear and practical. 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. I found a better balance between regular school and exam preparation. I was really happy with the lessons.

    Sota Suzuki

  • ACT

    It was good to see confidence returning over time. The tutor supported regular study, not only the lesson content. We would recommend the program to students and families in a similar situation.

    Beatrice DeLuca

  • A-Level

    A clear plan for the final weeks made priorities much easier to see. Breaking A-Level Computer Science into smaller pieces worked much better for me. I left the exam feeling that I had done what I could. I'm genuinely thankful to my tutor for being patient.

    Kerem Gokce

  • YÖS / TR-YÖS

    We weren't sure whether online lessons would be effective. With no more than six students, the tutor had time for everyone. The lessons started being followed without constant reminders from us. Flexible scheduling helped during a demanding school year. Seeing the change in our child made us very happy.

    Carmen Fidalgo

  • AP Exams

    We wanted our child to keep up with the school pace in AP US History. The tutor's close attention to weaker areas gave us confidence. We were pleased with the support we received.

    Erik Horvat

  • Digital SAT

    After my first attempt, I wanted the second round of preparation to feel more organized. I never felt awkward asking the same thing again. Seeing several versions of the same topic made unfamiliar questions less stressful. I'm genuinely thankful to my tutor for being patient.

    Mariana Cisneros

  • A-Level

    I wasn't starting from zero, but the same mistakes kept showing up in my mocks. Breaking A-Level Physics into smaller pieces worked much better for me. We could make the workload lighter during busy weeks at school or university. Separating calculation errors from content gaps made revision more useful. I found a better balance between regular school and exam preparation. I'm genuinely thankful to my tutor for being patient.
