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 had been studying alone, but my results stopped improving after a point. We didn't spend extra time on things I already knew. My mock results gradually became more consistent. I was really happy with the lessons.

    Somchai Panyasak

  • 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

  • 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

  • PTE Academic

    I had been studying alone, but my results stopped improving after a point. I found a better balance between regular school and exam preparation.

    Bo Xiao

  • PTE Academic

    I chose Write from Dictation this year and wanted to build a solid base from the beginning. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. I learned not to lose the rest of a listening task because I missed one word. A big thank you to my tutor for all the support :)

    Siddharth Arora

  • PTE Academic

    The feedback I received on Computer-Based Practice was clear and practical. Predicting the output helped me catch small logic errors. My preparation became much more regular and easier to track.

    Rui Saez

  • PTE Academic

    I had been studying alone, but my results stopped improving after a point. The group never had more than six students, so it was easy to stay involved. The writing feedback helped me stop repeating the same sentence-level errors. I stopped doing a huge amount one week and nothing the next. Questions from other students often helped me as well. It was an intense period, but it was worth it.

    Wei Yuan

  • PTE Academic

    The PTE Academic format felt unnecessarily confusing at first. Having the lesson move at my pace made the process feel much easier. I wasn't trying to learn new topics at the very last minute. Thanks to TestPrep for helping me stay on track.

    Elena Sequeira

  • PTE Academic

    After enough examples of the same question type, the repeated mistakes decreased. Breaking Write from Dictation into smaller pieces worked much better for me. I started noticing the reason for a mistake much faster. I'm genuinely thankful to my tutor for being patient.

    Zoe Rawson

  • PTE Academic

    I wasn't starting from zero, but the same mistakes kept showing up in my mocks. I found a better balance between regular school and exam preparation.

    Matilde Esteves

  • PTE Academic

    I developed a clearer way to return to the text during reading questions. I'm glad I worked with my tutor through this process.

    Putri Pratama

  • PTE Academic

    We weren't sure whether online lessons would be effective. Seeing the change in our child made us very happy.

    Harriet Mercer

  • PTE Academic

    I learned not to lose the rest of a listening task because I missed one word. I'm genuinely thankful to my tutor for being patient.

    Sebastian Zamora

  • PTE Academic

    Keeping up with PTE Academic while school was busy was harder than I expected. 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.

    Derya Duman

  • PTE Academic

    I learned not to lose the rest of a listening task because I missed one word. A big thank you to my tutor for all the support :)

    Camden Nichols

  • PTE Academic

    Breaking Speaking & Writing into smaller pieces worked much better for me. I started tracking the type of mistake, not just the number of questions I completed. 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. I left the exam feeling that I had done what I could. Thanks to everyone who supported me.

    Xinyi Pan

  • PTE Academic

    I finally understood what was going wrong in Listening. My confidence improved along with the results.

    Jonas Bakker

  • PTE Academic

    We weren't sure whether online lessons would be effective. We would recommend the program to students and families in a similar situation.

    Mert Celik

  • PTE Academic

    We wanted our child to keep up with the school pace in Reading. Preparation looked calmer and more organized closer to the exam. Seeing the change in our child made us very happy.

    Rodrigo Tellez

  • PTE Academic

    I finally understood what was going wrong in Repeat Sentence. By the end of each lesson, I knew what I was supposed to do during the week. It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. I started noticing the reason for a mistake much faster. Knowing what to study reduced a lot of the stress. Thanks to TestPrep for helping me stay on track.

    Alan Carranza

  • PTE Academic

    At the beginning, we knew very little about the PTE Academic system as parents. Preparation looked calmer and more organized closer to the exam.

    George Reid

  • PTE Academic

    I knew my target, but I didn't have a realistic routine for PTE Academic. Knowing what to study reduced a lot of the stress.
