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!

  • PTE Academic

    Over time, Describe Image became one of the most organized parts of my PTE Academic preparation. I developed a clearer way to return to the text during reading questions. I wasn't trying to learn new topics at the very last minute.

    Leon Koch

  • GRE General

    Balancing GRE General preparation with university and work was harder than I expected. I started tracking the type of mistake, not just the number of questions I completed. I started seeing shorter solutions that were easier to check under time pressure. Thanks to TestPrep for helping me stay on track.

    Sujin Oh

  • Digital SAT

    I was close to my target, but my results changed a lot from one test to the next. 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. Going back to the lesson recordings helped when I forgot a small step. Lesson times could fit around school, university or work. Thank you to my tutor and the TestPrep team.

    Marina Miranda

  • IGCSE / GCSE

    A good connection with the tutor developed quite quickly. Mistakes became something to work on rather than something to feel bad about. The overall experience was positive from beginning to end.

    Ivan Kaminski

  • GRE General

    In Quantitative Reasoning, timing was costing me more points than the content itself. I became much more comfortable asking questions in class.

    Louis Maillard

  • AP Exams

    Breaking AP World History into smaller pieces worked much better for me. My mock results gradually became more consistent.

    Manuela Zamora

  • LSAT

    Breaking Reading Comprehension into smaller pieces worked much better for me. I became much more comfortable asking questions in class.

    Carla Sarmiento

  • Digital SAT

    I was close to my target, but my results changed a lot from one test to the next. After a while, the questions started to feel much more familiar.

    Lara Kingston

  • YÖS / TR-YÖS

    I chose Geometry 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. Having the lesson move at my pace made the process feel much easier. We focused more on understanding what the problem asked than memorizing formulas. I became much more comfortable asking questions in class. I was really happy with the lessons.

    Mathis Lacroix

  • AP Exams

    When I started preparing for AP Exams, I wasn't sure what order to study things in. Near the exam, it was clear what to keep doing and what to stop. With data-heavy questions, I began reading the task before getting lost in the table. Thanks to everyone who supported me.

    Hugo Meunier

  • A-Level

    Our daughter needed regular support with A-Level Chemistry. The small group offered peer learning without making it hard to ask questions. Flexible scheduling helped during a demanding school year. We were able to follow the mock results regularly. The overall experience was positive from beginning to end.

    Luisa Brouwer

  • AP Exams

    The mocks showed where my time was actually being lost. The feedback I received on AP Macroeconomics was clear and practical. After a while, the questions started to feel much more familiar. A big thank you to my tutor for all the support :)

    Pietro Leone

  • LNAT

    When I started preparing for LNAT, I wasn't sure what order to study things in. I went into the exam much calmer than I would have before.

    Reid Keegan

  • AP Exams

    I was close to my target, but my results changed a lot from one test to the next. Going back to the lesson recordings helped when I forgot a small step. Separating calculation errors from content gaps made revision more useful. Thank you to the tutor who stayed supportive until the end.

    Keira Bennett

  • PTE Academic

    Having the lesson move at my pace made the process feel much easier. I finally understood what was going wrong in Describe Image. I started noticing the reason for a mistake much faster. Thanks to everyone who supported me.

    Ruoxi Chen

  • TOEFL iBT

    Our child had a clear goal but no steady study routine. We were pleased with the support we received.

    Noemie Maillard

  • YÖS / TR-YÖS

    The YÖS / TR-YÖS format felt unnecessarily confusing at first. Lesson times could fit around school, university or work. I found a better balance between regular school and exam preparation. Thanks to TestPrep for helping me stay on track.

    Hamish Kingston

  • AP Exams

    I finally understood what was going wrong in AP US Government. After a while, the questions started to feel much more familiar.

    Francesca Piras

  • UCAT

    I was close to my target, but my results changed a lot from one test to the next. A big thank you to my tutor for all the support :)

    Rory Spencer

  • UCAT

    I wasn't starting from zero, but the same mistakes kept showing up in my mocks. I stopped doing a huge amount one week and nothing the next. I worked on keeping a steady pace instead of rushing the easy questions. I was really happy with the lessons.

    Sakura Nishimura

  • IGCSE / GCSE

    The IGCSE / GCSE format felt unnecessarily confusing at first. I'm glad I worked with my tutor through this process.

    Hyejin Song

  • LSAT

    The feedback I received on Reading Comprehension was clear and practical. Knowing what to study reduced a lot of the stress.

    Quentin Berger

  • IGCSE / GCSE

    The feedback was clear enough that I always knew what to revise next. I'm glad I worked with my tutor through this process.

    Spencer Barrett

  • A-Level

    We noticed that the resources kept changing during independent study. The overall experience was positive from beginning to end.
