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!

  • 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

  • IB Diploma

    The IB Diploma format felt unnecessarily confusing at first. The plan changed with my mock and homework results, so the work never felt random. I worked on keeping a steady pace instead of rushing the easy questions. I'm genuinely thankful to my tutor for being patient.

    Felix Peeters

  • 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

  • A-Level

    Everyone recommended different resources and I kept switching between them. I'm genuinely thankful to my tutor for being patient.

    Fernanda Montoya

  • Digital SAT

    We wanted our child to keep up with the school pace in Craft & Structure. The plan was adjusted when school exams became busy. We quickly felt that the tutor was a good match.

    Mali Meechai

  • GMAT Focus

    After my first attempt, I wanted a calmer and more focused plan for the retake. Thank you to my tutor and the TestPrep team.

    Adrian Esteves

  • 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 :)

    Daan Smit

  • AP Exams

    I was doing questions for AP Comparative Government on my own but never had a steady routine. Thanks to TestPrep for helping me stay on track.

    Abbey Bevan

  • Digital SAT

    The feedback I received on Information & Ideas was clear and practical. I left the exam feeling that I had done what I could.

    Ozan Gokce

  • 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

  • Digital SAT

    Practicing in the real exam format made test day feel much less unfamiliar. I'm glad I worked with my tutor through this process.

    Radhika Sandhu

  • Digital SAT

    The feedback I received on Craft & Structure was clear and practical. I can now decide much faster when to move on from a question. I left the exam feeling that I had done what I could.

    Sude Bilgin

  • IB Diploma

    I chose IB Physics this year and wanted to build a solid base from the beginning. We could make the workload lighter during busy weeks at school or university. Past-paper questions showed me how different topics could appear together. Thanks to everyone who supported me.

    Matilda Templeton

  • IGCSE / GCSE

    After my first attempt, I wanted the second round of preparation to feel more organized. I went into the exam much calmer than I would have before.

    Kaito Sato

  • SSAT

    I worked on keeping a steady pace instead of rushing the easy questions. Thanks to everyone who supported me.

    Bao Hoang

  • IGCSE / GCSE

    I was taking IGCSE Art and Design at school, but getting used to the exam questions took time. I found a better balance between regular school and exam preparation.

    Liam Langley

  • Digital SAT

    We noticed that the resources kept changing during independent study. Online lessons made it possible to continue without losing time on travel. Joining lessons willingly was one of the clearest signs for us. Being able to fit lessons around school made the process easier. The tutor supported regular study, not only the lesson content. We were happy with both the teaching and the communication.

    Kennedy Coleman

  • GMAT Focus

    With data-heavy questions, I began reading the task before getting lost in the table. I'm glad I worked with my tutor through this process.

    Volkan Akbulut

  • YÖS / TR-YÖS

    Breaking IQ & Logic into smaller pieces worked much better for me. The plan changed with my mock and homework results, so the work never felt random. We focused more on understanding what the problem asked than memorizing formulas. I went into the exam much calmer than I would have before. I wasn't trying to learn new topics at the very last minute. I was really happy with the lessons.

    Agustina Cuellar

  • Digital SAT

    We didn't spend extra time on things I already knew. Over time, Geometry & Trigonometry became one of the most organized parts of my Digital SAT preparation. I went into the exam much calmer than I would have before. I was really happy with the lessons.

    Moritz Conrad

  • Digital SAT

    I finally understood what was going wrong in Bluebook adaptif modüller. Knowing what to study reduced a lot of the stress.

    Clement Gaudin

  • A-Level

    Everyone recommended different resources and I kept switching between them. After each test, we looked beyond the score and reviewed the type of each mistake. There was no overnight miracle, but the progress was easy to see. Thanks to everyone who supported me.

    Melis Kurt

  • GRE General

    After my first attempt, I wanted a calmer and more focused plan for the retake. My confidence improved along with the results.

    Brooke Menzies

  • Digital SAT

    I was doing questions for Problem Solving & Data Analysis on my own but never had a steady routine. After each test, we looked beyond the score and reviewed the type of each mistake. I started seeing shorter solutions that were easier to check under time pressure. I started tracking the type of mistake, not just the number of questions I completed. Full-length mocks helped me get used to the real exam pace. A big thank you to my tutor for all the support :)
