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!

  • GRE General

    I had collected too many resources without knowing when to use any of them. Having the lesson move at my pace made the process feel much easier. Practicing in the real exam format made test day feel much less unfamiliar. I never felt awkward asking the same thing again. The preparation felt calmer than I expected.

    Chloe Connolly

  • GRE General

    A quick check after each answer helped me catch small mistakes. I'm glad I worked with my tutor through this process.

    Rui Antunes

  • GRE General

    The feedback I received on Section-Adaptive Strategy was clear and practical. I started noticing the reason for a mistake much faster.

    Oscar Murray

  • GRE General

    Balancing GRE General preparation with university and work was harder than I expected. Going back to the lesson recordings helped when I forgot a small step. I learned not to spend the same amount of time on every line of a long text. Thanks to TestPrep for helping me stay on track.

    Lara Lambert

  • GRE General

    In Text Completion, timing was costing me more points than the content itself. The feedback I received on Text Completion was clear and practical. The plan changed with my mock and homework results, so the work never felt random. A lot of my mistakes came from rushing through the wording of the question. My confidence improved along with the results. Thanks to everyone who supported me.

    Riya Bhatia

  • GRE General

    Over time, Sentence Equivalence became one of the most organized parts of my GRE General preparation. My preparation became much more regular and easier to track.

    Darcy OConnell

  • GRE General

    In Analytical Writing, timing was costing me more points than the content itself. The preparation felt calmer than I expected.

    Seo Yang

  • GRE General

    I came back to Data Analysis after a long break and wasn't sure where to begin. Breaking Data Analysis into smaller pieces worked much better for me. Going back to the lesson recordings helped when I forgot a small step. I started seeing shorter solutions that were easier to check under time pressure. I found a better balance between regular school and exam preparation. Thanks to everyone who supported me.

    Sooyoung Lee

  • GRE General

    The mocks showed where my time was actually being lost. I finally understood what was going wrong in Section-Adaptive Strategy. My confidence improved along with the results. Thanks to everyone who supported me.

    Dev Desai

  • GRE General

    The feedback I received on Data Analysis was clear and practical. My mock results gradually became more consistent.

    Eleanor Baxter

  • GRE General

    We didn't spend extra time on things I already knew. The feedback I received on Section-Adaptive Strategy was clear and practical. I left the exam feeling that I had done what I could. Thanks to TestPrep for helping me stay on track.

    Milena Madsen

  • GRE General

    The feedback I received on Section-Adaptive Strategy was clear and practical. My tutor made it easy to ask questions from the first lesson. I worked on keeping a steady pace instead of rushing the easy questions. I went into the exam much calmer than I would have before. I found a better balance between regular school and exam preparation. Thank you to my tutor and the TestPrep team.

    Varun Shah

  • GRE General

    Balancing GRE General preparation with university and work was harder than I expected. 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. Thank you to the tutor who stayed supportive until the end.

    Claire Picard

  • GRE General

    Balancing GRE General preparation with university and work was harder than I expected. My tutor could see my reasoning and usually found the source of an error quickly. My preparation became much more regular and easier to track. I'm genuinely thankful to my tutor for being patient.

    Cody Baird

  • GRE General

    Over time, Text Completion became one of the most organized parts of my GRE General preparation. By the end of each lesson, I knew what I was supposed to do during the week. I stopped choosing answers by feel and started looking for evidence in the passage. I went into the exam much calmer than I would have before. My preparation became much more regular and easier to track. Thank you to my tutor and the TestPrep team.

    Levi Hume

  • GRE General

    Brooke Menzies

  • GRE General

    I came back to Verbal Reasoning after a long break and wasn't sure where to begin. I stopped doing a huge amount one week and nothing the next. Full-length mocks helped me get used to the real exam pace. Discussing why the other choices were wrong helped more than I expected. I left the exam feeling that I had done what I could. I'm genuinely thankful to my tutor for being patient.

    Marko Holm

  • GRE General

    Lesson times could fit around school, university or work. Over time, Quantitative Reasoning became one of the most organized parts of my GRE General preparation. After a while, the questions started to feel much more familiar. Thank you to the tutor who stayed supportive until the end.

    Tao Zhu

  • GRE General

    Having the lesson move at my pace made the process feel much easier. The feedback I received on Verbal Reasoning was clear and practical. My confidence improved along with the results. A big thank you to my tutor for all the support :)

    Franco Salazar

  • GRE General

    I finally understood what was going wrong in Sentence Equivalence. When I got something wrong, we looked at why I chose that answer instead of only checking the solution.

Thanks to everyone who supported me.
