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!

  • IGCSE / GCSE

    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. A clear plan for the final weeks made priorities much easier to see. I understood that the portfolio needed to show the process, not only the finished piece. I became much more comfortable asking questions in class. A big thank you to my tutor for all the support :)

    Kayla Donovan

  • PTE Academic

    Breaking Speaking & Writing into smaller pieces worked much better for me. My mock results gradually became more consistent.

    Tsubasa Yoshida

  • UCAT

    I chose Decision Making this year and wanted to build a solid base from the beginning. I started noticing the reason for a mistake much faster.

    Kaito Hashimoto

  • IMAT

    Everyone recommended different resources and I kept switching between them. It was an intense period, but it was worth it.

    Tao Wu

  • AP Exams

    I was close to my target, but my results changed a lot from one test to the next. I finally understood what was going wrong in AP Physics 2. We could make the workload lighter during busy weeks at school or university. Once I understood the reasons behind the facts, the questions felt less random. My confidence improved along with the results. The preparation felt calmer than I expected.

    Blake Haines

  • YÖS / TR-YÖS

    Breaking Geometry into smaller pieces worked much better for me. Knowing what to study reduced a lot of the stress.

    Claire Blanchard

  • IB Diploma

    Once I understood the reasons behind the facts, the questions felt less random. Thanks to everyone who supported me.

    Ananya Ahuja

  • GRE General

    After my first attempt, I wanted a calmer and more focused plan for the retake. We could make the workload lighter during busy weeks at school or university. My written answers became shorter, clearer and easier to follow. The preparation felt calmer than I expected.

    Junseo Sung

  • UCAT

    Lesson times could fit around school, university or work. Breaking Situational Judgement into smaller pieces worked much better for me. Knowing what to study reduced a lot of the stress. I was really happy with the lessons.

    Ingrid Kolar

  • Digital SAT

    I wasn't starting from zero, but the same mistakes kept showing up in my mocks. My tutor could see my reasoning and usually found the source of an error quickly. I worked on keeping a steady pace instead of rushing the easy questions. Going back to the lesson recordings helped when I forgot a small step. A big thank you to my tutor for all the support :)

    Camille Marchand

  • Digital SAT

    Keeping up with Digital SAT while school was busy was harder than I expected. Going back to the lesson recordings helped when I forgot a small step. My tutor could see my reasoning and usually found the source of an error quickly. A quick check after each answer helped me catch small mistakes. There was no overnight miracle, but the progress was easy to see. Thanks to TestPrep for helping me stay on track.

    Goncalo Molina

  • SSAT

    After the first attempt, we looked for a calmer plan for the retake. Mistakes became something to work on rather than something to feel bad about. The question bank made independent work between lessons much clearer. Communication with the team was straightforward and our questions were answered. Thank you sincerely to everyone involved.

    Joel Ingram

  • SSAT

    I can now decide much faster when to move on from a question. I'm glad I worked with my tutor through this process.

    Alana Clarke

  • AP Exams

    I was doing questions for AP Computer Science Principles on my own but never had a steady routine. We didn't spend extra time on things I already knew. Predicting the output helped me catch small logic errors. My tutor usually asked me to explain my thinking before stepping in. Lesson times could fit around school, university or work. It was an intense period, but it was worth it.

    Connor Hartley

  • IGCSE / GCSE

    Breaking IGCSE Environmental Management into smaller pieces worked much better for me. Once I understood the reasons behind the facts, the questions felt less random. I left the exam feeling that I had done what I could.

    Diego Rojas

  • IGCSE / GCSE

    As the exam got closer, I wasn't sure what I should actually review. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Separating strategy mistakes from content gaps made progress much quicker. I was really happy with the lessons.

    Meilin Huang

  • IB Diploma

    I wasn't starting from zero, but the same mistakes kept showing up in my mocks. A big thank you to my tutor for all the support :)

    Bram Peeters

  • ACT

    As the exam got closer, I wasn't sure what I should actually review. I was really happy with the lessons.

    Ayu Gunawan

  • AP Exams

    Our daughter needed regular support with AP Biology. Online lessons made it possible to continue without losing time on travel. A good connection with the tutor developed quite quickly. The tutor's close attention to weaker areas gave us confidence. Mistakes became something to work on rather than something to feel bad about. We thank the tutor and the TestPrep team.

    Nazli Gokce

  • 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

  • IGCSE / GCSE

    Our son's school schedule was already very busy. We were able to follow the mock results regularly.

    Piper Sinclair

  • AP Exams

    The feedback I received on AP Psychology was clear and practical. There was no overnight miracle, but the progress was easy to see.

    Harrison Teague

  • IB Diploma

    I learned to make a short plan before starting a long response. It was an intense period, but it was worth it.
