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!

  • TOEFL iBT

    During the intensive review, we returned to real gaps instead of restarting everything. Over time, Integrated Tasks became one of the most organized parts of my TOEFL iBT preparation. I became much more comfortable asking questions in class. Thank you to my tutor and the TestPrep team.

    Dong Deng

  • TOEFL iBT

    We noticed that the resources kept changing during independent study. The tutor supported regular study, not only the lesson content.

    Maja Richter

  • TOEFL iBT

    We reduced the memorized phrases so my answers sounded more natural. It was an intense period, but it was worth it.

    Saki Ota

  • TOEFL iBT

    The feedback I received on Integrated Tasks was clear and practical. My tutor usually asked me to explain my thinking before stepping in. I learned not to lose the rest of a listening task because I missed one word. I wasn't trying to learn new topics at the very last minute. I went into the exam much calmer than I would have before. A big thank you to my tutor for all the support :)

    Sameer Sharma

  • TOEFL iBT

    I had been studying alone, but my results stopped improving after a point. The preparation felt calmer than I expected.

    Ginevra Ferri

  • TOEFL iBT

    Our child wasn't sure how to organize the preparation for TOEFL iBT. Online lessons made it possible to continue without losing time on travel. The lessons started being followed without constant reminders from us. The tutor's close attention to weaker areas gave us confidence. We were able to follow the mock results regularly. We were pleased with the support we received.

    Elena Amato

  • TOEFL iBT

    A clear plan for the final weeks made priorities much easier to see. Breaking Listening into smaller pieces worked much better for me. Knowing what to study reduced a lot of the stress. Thanks to everyone who supported me.

    Amanda Silveira

  • TOEFL iBT

    I chose Listening this year and wanted to build a solid base from the beginning. I became much more comfortable asking questions in class.

    Delaney Porter

  • TOEFL iBT

    I finally understood what was going wrong in Writing. I found a better balance between regular school and exam preparation.

    Amelie Delorme

  • TOEFL iBT

    After my first attempt, I wanted a calmer and more focused plan for the retake. My mock results gradually became more consistent.

    Rahul Dutta

  • TOEFL iBT

    Breaking Speaking into smaller pieces worked much better for me. I developed a clearer way to return to the text during reading questions. My mock results gradually became more consistent.

    Zoe Rafferty

  • TOEFL iBT

    We didn't spend extra time on things I already knew. Over time, Speaking became one of the most organized parts of my TOEFL iBT preparation. Knowing what to study reduced a lot of the stress. It was an intense period, but it was worth it.

    Tommaso Coppola

  • TOEFL iBT

    Balancing TOEFL iBT preparation with university and work was harder than I expected. We didn't spend extra time on things I already knew. The writing feedback helped me stop repeating the same sentence-level errors. My tutor made it easy to ask questions from the first lesson. My tutor could see my reasoning and usually found the source of an error quickly. I'm glad I worked with my tutor through this process.

    Miles Stanton

  • TOEFL iBT

    The TOEFL iBT format felt unnecessarily confusing at first. One bad mock no longer made me want to drop the whole plan. Lesson times could fit around school, university or work. I developed a clearer way to return to the text during reading questions. After a while, the questions started to feel much more familiar. I'm genuinely thankful to my tutor for being patient.

    Evie Keating

  • TOEFL iBT

    Our daughter needed regular support with Listening. Mistakes became something to work on rather than something to feel bad about. With no more than six students, the tutor had time for everyone. Flexible scheduling helped during a demanding school year. It was good to see confidence returning over time. The overall experience was positive from beginning to end.

    Larissa Marques

  • TOEFL iBT

    Balancing TOEFL iBT preparation with university and work was harder than I expected. The class felt relaxed enough to ask questions without overthinking it. We reduced the memorized phrases so my answers sounded more natural. My tutor made it easy to ask questions from the first lesson. The group never had more than six students, so it was easy to stay involved. A big thank you to my tutor for all the support :)

    Finley Baxter

  • TOEFL iBT

    I came back to Speaking after a long break and wasn't sure where to begin. Even in a group lesson, the tutor knew where each of us stood. I developed a clearer way to return to the text during reading questions. My tutor made it easy to ask questions from the first lesson. Questions from other students often helped me as well. Thank you to the tutor who stayed supportive until the end.

    Efe Tekin

  • TOEFL iBT

    Breaking Speaking into smaller pieces worked much better for me. I started noticing the reason for a mistake much faster.

    Alessia Bellini

  • TOEFL iBT

    In Reading, timing was costing me more points than the content itself. Thank you to my tutor and the TestPrep team.

    Alejandra Mena

  • TOEFL iBT

    Even in a group lesson, the tutor knew where each of us stood. The feedback I received on Integrated Tasks was clear and practical. I found a better balance between regular school and exam preparation. Thank you to the tutor who stayed supportive until the end.

    Frieda Klein

  • TOEFL iBT

    The feedback I received on Reading was clear and practical. I started tracking the type of mistake, not just the number of questions I completed. I learned not to lose the rest of a listening task because I missed one word. My preparation became much more regular and easier to track. Thanks to everyone who supported me.

    Seojun Moon

  • TOEFL iBT

    I finally understood what was going wrong in Reading. I developed a clearer way to return to the text during reading questions. I found a better balance between regular school and exam preparation.

    Aline Correia

  • TOEFL iBT

    Communication with the team was straightforward and our questions were answered. We would recommend the program to students and families in a similar situation.

    Larissa Lima

  • TOEFL iBT

    Experiencing the exam format beforehand made test day much less stressful. Over time, Speaking became one of the most organized parts of my TOEFL iBT preparation. Knowing what to study reduced a lot of the stress. It was an intense period, but it was worth it.
