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.

  • IB Diploma

    The feedback I received on IB TITC was clear and practical. There was no overnight miracle, but the progress was easy to see.

    Sakura Inoue

  • A-Level

    When I started preparing for A-Level, I wasn't sure what order to study things in. One bad mock no longer made me want to drop the whole plan. I learned to make a short plan before starting a long response. I was really happy with the lessons.

    Bonnie Stanton

  • UCAT

    Our child wasn't sure how to organize the preparation for UCAT. It was good to see confidence returning over time.

    Sujin Min

  • A-Level

    I finally understood what was going wrong in A-Level History. I started noticing the reason for a mistake much faster.

    Oscar Lambert

  • IELTS Academic

    Everyone recommended different resources and I kept switching between them. Over time, Listening became one of the most organized parts of my IELTS Academic preparation. My tutor made it easy to ask questions from the first lesson. We reduced the memorized phrases so my answers sounded more natural. My mock results gradually became more consistent. Thank you to the tutor who stayed supportive until the end.

    Wyatt Ellison

  • IGCSE / GCSE

    I was close to my target, but my results changed a lot from one test to the next. My tutor could see my reasoning and usually found the source of an error quickly. I became much more comfortable asking questions in class. Thanks to everyone who supported me.

    Aylin Kurt

  • TOEFL iBT

    I knew my target, but I didn't have a realistic routine for TOEFL iBT. A big thank you to my tutor for all the support :)

    Bruno Nunes

  • ACT

    We weren't sure whether online lessons would be effective. Online lessons made it possible to continue without losing time on travel. We were pleased with the support we received.

    Leticia Leite

  • AP Exams

    During the intensive review, we returned to real gaps instead of restarting everything. The feedback I received on AP Comparative Government was clear and practical. I wasn't trying to learn new topics at the very last minute. It was an intense period, but it was worth it.

    Isla Kirk

  • IELTS Academic

    Mistakes became something to work on rather than something to feel bad about. Flexible scheduling helped during a demanding school year. Seeing the change in our child made us very happy.

    Mateo Lemus

  • IGCSE / GCSE

    At the beginning, we knew very little about the IGCSE / GCSE system as parents. Flexible scheduling helped during a demanding school year.

    Imogen Tarrant

  • SSAT

    What annoyed me most was losing easy points because I rushed. I found a better balance between regular school and exam preparation.

    Gabriel Nunes

  • GRE General

    Having the lesson move at my pace made the process feel much easier. The feedback I received on Verbal Reasoning was clear and practical. My confidence improved along with the results. A big thank you to my tutor for all the support :)

    Caitlin McLean

  • AP Exams

    After my first attempt, I wanted the second round of preparation to feel more organized. Thanks to TestPrep for helping me stay on track.

    Riley Mercer

  • UCAT

    Mistakes became something to work on rather than something to feel bad about. Preparation looked calmer and more organized closer to the exam. The overall experience was positive from beginning to end.

    Lauren Foster

  • IMAT

    I was close to my target, but my results changed a lot from one test to the next. Knowing what to study reduced a lot of the stress.

    Arnav Khanna

  • IB Diploma

    Over time, IB Physics became one of the most organized parts of my IB Diploma preparation. Once I understood the reasons behind the facts, the questions felt less random. After a while, the questions started to feel much more familiar.

    Rafaela Cunha

  • A-Level

    I became much more careful with graphs, experiments and data-based questions. Thank you to the tutor who stayed supportive until the end.

    Megan Hargreaves

  • IMAT

    The IMAT format felt unnecessarily confusing at first. Breaking Chemistry into smaller pieces worked much better for me. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Once I understood the reasons behind the facts, the questions felt less random. There was no overnight miracle, but the progress was easy to see. A big thank you to my tutor for all the support :)

    Minho Kim

  • GRE General

    The feedback I received on Section-Adaptive Strategy was clear and practical. I became much more comfortable asking questions in class.

    Hailey Kendrick

  • IB Diploma

    We wanted our child to keep up with the school pace in IB English A. Joining lessons willingly was one of the clearest signs for us. Thank you sincerely to everyone involved.

    Parker McAllister

  • YÖS / TR-YÖS

    I chose IQ & Logic this year and wanted to build a solid base from the beginning. There was no overnight miracle, but the progress was easy to see.

    Sienna Cormack

  • GMAT Focus

    I had been studying alone, but my results stopped improving after a point. Breaking Data Sufficiency into smaller pieces worked much better for me. My tutor made it easy to ask questions from the first lesson. Balancing Quant and Verbal in the same week worked better than studying them in blocks. My mock results gradually became more consistent. Thank you to my tutor and the TestPrep team.

    Eliza Ainsworth

  • AP Exams

    Keeping up with AP Exams while school was busy was harder than I expected. Breaking AP Research into smaller pieces worked much better for me. By the end of each lesson, I knew what I was supposed to do during the week. Knowing the criteria from the start made the whole task less vague. There was no overnight miracle, but the progress was easy to see. Thanks to everyone who supported me.
