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.

  • UCAT

    Our son's school schedule was already very busy. Individual lesson time was used around our child's actual needs. Online lessons made it possible to continue without losing time on travel. The tutor supported regular study, not only the lesson content. We thank the tutor and the TestPrep team.

    Ayaka Matsumoto

  • UCAT

    I wasn't starting from zero, but the same mistakes kept showing up in my mocks. It was an intense period, but it was worth it.

    Liam Gibson

  • UCAT

    Seeing several versions of the same topic made unfamiliar questions less stressful. I was really happy with the lessons.

    Rocio Campos

  • UCAT

    As the exam got closer, I wasn't sure what I should actually review. I started noticing the reason for a mistake much faster.

    Hyunwoo Sung

  • UCAT

    When I started preparing for UCAT, I wasn't sure what order to study things in. It was an intense period, but it was worth it.

    Henrik Horvat

  • UCAT

    Breaking Verbal Reasoning into smaller pieces worked much better for me. I started tracking the type of mistake, not just the number of questions I completed. Discussing why the other choices were wrong helped more than I expected. I started noticing the reason for a mistake much faster. After a while, the questions started to feel much more familiar. Thank you to the tutor who stayed supportive until the end.

    Bailey Sanderson

  • UCAT

    I was taking Time Management at school, but getting used to the exam questions took time. Having the lesson move at my pace made the process feel much easier. I started noticing the reason for a mistake much faster. Thank you to my tutor and the TestPrep team.

    Connor Bevan

  • UCAT

    The feedback I received on Quantitative Reasoning was clear and practical. My confidence improved along with the results.

    Luka Svoboda

  • UCAT

    The UCAT format felt unnecessarily confusing at first. By the end of each lesson, I knew what I was supposed to do during the week. I can now decide much faster when to move on from a question. It was an intense period, but it was worth it.

    Pooja Bhatia

  • UCAT

    The UCAT format felt unnecessarily confusing at first. There was no overnight miracle, but the progress was easy to see.

    Nico Neumann

  • UCAT

    The lessons started being followed without constant reminders from us. It was good to see confidence returning over time. We quickly felt that the tutor was a good match.

    Victor Santana

  • UCAT

    What annoyed me most was losing easy points because I rushed. My tutor usually asked me to explain my thinking before stepping in. Working across different difficulty levels made new questions feel less surprising. I can now decide much faster when to move on from a question. After a while, the questions started to feel much more familiar. A big thank you to my tutor for all the support :)

    Rui Chen

  • UCAT

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

    Holly Ingram

  • UCAT

    I was taking Quantitative Reasoning 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. I started seeing shorter solutions that were easier to check under time pressure. I was really happy with the lessons.

    Evie Cormack

  • UCAT

    I was doing questions for Time Management on my own but never had a steady routine. We could make the workload lighter during busy weeks at school or university. Sorting mistakes after each mock changed the way I studied. A big thank you to my tutor for all the support :)

    Filippo Gatti

  • UCAT

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

    Kaito Hashimoto

  • UCAT

    Lesson times could fit around school, university or work. Breaking Situational Judgement into smaller pieces worked much better for me. Knowing what to study reduced a lot of the stress. I was really happy with the lessons.

    Ingrid Kolar

  • UCAT

    I used the question bank regularly to return to weaker topics. Over time, Decision Making became one of the most organized parts of my UCAT preparation. I went into the exam much calmer than I would have before. Thanks to everyone who supported me.

    Varun Jadhav

  • UCAT

    I was taking Time Management at school, but getting used to the exam questions took time. I started tracking the type of mistake, not just the number of questions I completed. Timed work showed exactly which section was slowing me down. I'm glad I worked with my tutor through this process.

    Colin Patterson

  • UCAT

    I chose Time Management this year and wanted to build a solid base from the beginning. Going back to the lesson recordings helped when I forgot a small step. We didn't spend extra time on things I already knew. Sorting mistakes after each mock changed the way I studied. There was no overnight miracle, but the progress was easy to see. I'm glad I worked with my tutor through this process.

    Mette Jovic

  • UCAT

    I was doing questions for Quantitative Reasoning on my own but never had a steady routine. Having the lesson move at my pace made the process feel much easier. I started seeing shorter solutions that were easier to check under time pressure. My tutor made it easy to ask questions from the first lesson. Thanks to TestPrep for helping me stay on track.

    Pietro Grimaldi

  • UCAT

    Our child had a clear goal but no steady study routine. A good connection with the tutor developed quite quickly. We quickly felt that the tutor was a good match.

    Lucas Vieira

  • UCAT

    I was taking Verbal Reasoning at school, but getting used to the exam questions took time. A big thank you to my tutor for all the support :)

    Bea Valdez

  • UCAT

    Our daughter needed regular support with Situational Judgement. 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 lessons started being followed without constant reminders from us. We quickly felt that the tutor was a good match.
