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.

  • PTE Academic

    I was close to my target, but my results changed a lot from one test to the next. The class felt relaxed enough to ask questions without overthinking it. My mock results gradually became more consistent. Thanks to everyone who supported me.

    Nikola Kowalski

  • PTE Academic

    I came back to Write from Dictation after a long break and wasn't sure where to begin. The mocks showed where my time was actually being lost. My mock results gradually became more consistent. Thanks to TestPrep for helping me stay on track.

    Blake Atkinson

  • PTE Academic

    Our daughter needed regular support with Repeat Sentence. Communication with the team was straightforward and our questions were answered. Online lessons made it possible to continue without losing time on travel. Being able to fit lessons around school made the process easier. A good connection with the tutor developed quite quickly. We quickly felt that the tutor was a good match.

    Joonho Jin

  • PTE Academic

    We weren't sure whether online lessons would be effective. Being able to fit lessons around school made the process easier. We were pleased with the support we received.

    Grace Hartley

  • PTE Academic

    It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. I'm genuinely thankful to my tutor for being patient.

    Hayden Dwyer

  • PTE Academic

    Over time, Repeat Sentence became one of the most organized parts of my PTE Academic preparation. It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. There was no overnight miracle, but the progress was easy to see.

    Hannah Langley

  • PTE Academic

    The PTE Academic format felt unnecessarily confusing at first. The group never had more than six students, so it was easy to stay involved. I left the exam feeling that I had done what I could. Thanks to TestPrep for helping me stay on track.

    Cheng Shi

  • PTE Academic

    We weren't sure whether online lessons would be effective. Being able to fit lessons around school made the process easier. Thank you sincerely to everyone involved.

    Sari Setiawan

  • PTE Academic

    After the first attempt, we looked for a calmer plan for the retake. Regular work on similar question types reduced repeated mistakes. The tutor supported regular study, not only the lesson content. The plan was adjusted when school exams became busy. We would recommend the program to students and families in a similar situation.

    Nanami Fujita

  • PTE Academic

    We noticed that the resources kept changing during independent study. The lessons started being followed without constant reminders from us. Being able to fit lessons around school made the process easier. The tutor supported regular study, not only the lesson content. Mistakes became something to work on rather than something to feel bad about. We thank the tutor and the TestPrep team.

    Quang Cao

  • PTE Academic

    I came back to Computer-Based Practice after a long break and wasn't sure where to begin. Going back to the lesson recordings helped when I forgot a small step. My written code answers became much more organized. Thanks to TestPrep for helping me stay on track.

    Linnea Bakke

  • PTE Academic

    I came back to Describe Image after a long break and wasn't sure where to begin. Having the lesson move at my pace made the process feel much easier. I learned not to lose the rest of a listening task because I missed one word. One bad mock no longer made me want to drop the whole plan. Lesson times could fit around school, university or work. The preparation felt calmer than I expected.

    Can Bozkurt

  • PTE Academic

    Our child had a clear goal but no steady study routine. A good connection with the tutor developed quite quickly. The small group offered peer learning without making it hard to ask questions. It was good to see confidence returning over time. We quickly felt that the tutor was a good match.

    Fernanda Tellez

  • PTE Academic

    As the exam got closer, I wasn't sure what I should actually review. Going back to the lesson recordings helped when I forgot a small step. Questions from other students often helped me as well. We reduced the memorized phrases so my answers sounded more natural. I became much more comfortable asking questions in class. Thank you to my tutor and the TestPrep team.

    Alessio Giordano

  • PTE Academic

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

    Miles Harrison

  • PTE Academic

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

    Jack Whelan

  • PTE Academic

    Our child wasn't sure how to organize the preparation for PTE Academic. The lessons started being followed without constant reminders from us. The plan was adjusted when school exams became busy. The question bank made independent work between lessons much clearer. Mistakes became something to work on rather than something to feel bad about. We thank the tutor and the TestPrep team.

    Emi Kato

  • PTE Academic

    Breaking Computer-Based Practice into smaller pieces worked much better for me. My tutor usually asked me to explain my thinking before stepping in. Before coding, I began thinking about which structure actually fit the problem. Knowing what to study reduced a lot of the stress. I found a better balance between regular school and exam preparation. A big thank you to my tutor for all the support :)
