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.

  • LSAT

    I stopped choosing answers by feel and started looking for evidence in the passage. It was an intense period, but it was worth it.

    Valentina Ocampo

  • LSAT

    Breaking Logical Reasoning into smaller pieces worked much better for me. Discussing why the other choices were wrong helped more than I expected. My mock results gradually became more consistent.

    Astrid Ekstrom

  • LSAT

    Over time, Reading Comprehension became one of the most organized parts of my LSAT preparation. A lot of my mistakes came from rushing through the wording of the question. I became much more comfortable asking questions in class.

    Elif Bozkurt

  • LSAT

    After my first attempt, I wanted a calmer and more focused plan for the retake. One bad mock no longer made me want to drop the whole plan. My written answers became shorter, clearer and easier to follow. Thank you to my tutor and the TestPrep team.

    Sora Cho

  • LSAT

    I had collected too many resources without knowing when to use any of them. I finally understood what was going wrong in Argumentative Writing. I stopped doing a huge amount one week and nothing the next. I stopped choosing answers by feel and started looking for evidence in the passage. My confidence improved along with the results. I'm genuinely thankful to my tutor for being patient.

    Haruka Ono

  • LSAT

    Gabriela Quiroga

  • LSAT

    Over time, Argumentative Writing became one of the most organized parts of my LSAT preparation. I wasn't trying to learn new topics at the very last minute.

    Sander Werner

  • LSAT

    I came back to Reading Comprehension after a long break and wasn't sure where to begin. Knowing what to study reduced a lot of the stress.

    Davide Coppola

  • LSAT

    I knew my target, but I didn't have a realistic routine for LSAT. The plan changed with my mock and homework results, so the work never felt random. I learned not to spend the same amount of time on every line of a long text. Thank you to my tutor and the TestPrep team.

    Ming Ye

  • LSAT

    I had been studying alone, but my results stopped improving after a point. A big thank you to my tutor for all the support :)

    Xiaoyu Shi

  • LSAT

    After my first attempt, I wanted a calmer and more focused plan for the retake. Near the exam, it was clear what to keep doing and what to stop. A clear plan for the final weeks made priorities much easier to see. I learned not to spend the same amount of time on every line of a long text. I found a better balance between regular school and exam preparation. Thank you to the tutor who stayed supportive until the end.

    Jordan Callahan

  • LSAT

    My mock scores were inconsistent, so it was hard to judge my actual level. Near the exam, it was clear what to keep doing and what to stop. The group never had more than six students, so it was easy to stay involved. Discussing why the other choices were wrong helped more than I expected. There was no overnight miracle, but the progress was easy to see. A big thank you to my tutor for all the support :)

    Elisa Coppola

  • LSAT

    Having the lesson move at my pace made the process feel much easier. Breaking Logical Reasoning into smaller pieces worked much better for me. There was no overnight miracle, but the progress was easy to see. The preparation felt calmer than I expected.
