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!

  • A-Level

    Keeping up with A-Level while school was busy was harder than I expected. I stopped doing a huge amount one week and nothing the next. Using the mark scheme to review my own answer was surprisingly helpful. Thanks to TestPrep for helping me stay on track.

    Abbey Fletcher

  • SSAT

    I was close to my target, but my results changed a lot from one test to the next. My preparation became much more regular and easier to track.

    Hamish OBrien

  • LSAT

    Balancing LSAT preparation with university and work was harder than I expected. My tutor usually asked me to explain my thinking before stepping in. I stopped choosing answers by feel and started looking for evidence in the passage. A big thank you to my tutor for all the support :)

    Hao Feng

  • AP Exams

    Over time, AP English Language became one of the most organized parts of my AP Exams preparation. I learned not to spend the same amount of time on every line of a long text. My confidence improved along with the results.

    Marcelo Borges

  • UCAT

    As the exam got closer, I wasn't sure what I should actually review. A big thank you to my tutor for all the support :)

    Daeun Song

  • A-Level

    After the first attempt, we looked for a calmer plan for the retake. The plan was adjusted when school exams became busy. Returning to actual gaps instead of restarting everything saved time. We were able to follow the mock results regularly. Preparation looked calmer and more organized closer to the exam. The overall experience was positive from beginning to end.

    Luana Rezende

  • SSAT

    Everyone recommended different resources and I kept switching between them. Near the exam, it was clear what to keep doing and what to stop. I learned not to spend the same amount of time on every line of a long text. The preparation felt calmer than I expected.

    Bianca Miranda

  • UCAT

    When I started preparing for UCAT, I wasn't sure what order to study things in. I'm glad I worked with my tutor through this process.

    Aditya Naidu

  • AP Exams

    As the exam got closer, I wasn't sure what I should actually review. My tutor could see my reasoning and usually found the source of an error quickly. Connecting examples back to the main point made my writing more consistent. We could make the workload lighter during busy weeks at school or university. Lesson times could fit around school, university or work. I'm glad I worked with my tutor through this process.

    Thijs Neumann

  • Digital SAT

    I was doing questions for Craft & Structure on my own but never had a steady routine. My mock results gradually became more consistent.

    Lara Sutherland

  • SSAT

    I was taking Verbal at school, but getting used to the exam questions took time. Lesson times could fit around school, university or work. I learned not to spend the same amount of time on every line of a long text. I stopped doing a huge amount one week and nothing the next. Having the lesson move at my pace made the process feel much easier. Thanks to TestPrep for helping me stay on track.

    Jordan Ridley

  • AP Exams

    The feedback I received on AP Computer Science A was clear and practical. I never felt awkward asking the same thing again. The lessons where I found the bug myself were the ones I remembered best. 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'm genuinely thankful to my tutor for being patient.

    Zora Lindberg

  • IGCSE / GCSE

    After the first attempt, we looked for a calmer plan for the retake. We were pleased with the support we received.

    Avery Whitaker

  • IGCSE / GCSE

    Over time, IGCSE Chemistry became one of the most organized parts of my IGCSE / GCSE preparation. My tutor made it easy to ask questions from the first lesson. I became much more careful with graphs, experiments and data-based questions. I started noticing the reason for a mistake much faster. After a while, the questions started to feel much more familiar. It was an intense period, but it was worth it.

    Blake Carver

  • UCAT

    Keeping up with UCAT while school was busy was harder than I expected. It was an intense period, but it was worth it.

    Cole Abbott

  • UCAT

    Mistakes became something to work on rather than something to feel bad about. We were happy with both the teaching and the communication.

    Riley Rowntree

  • IB Diploma

    After my first attempt, I wanted the second round of preparation to feel more organized. Having the lesson move at my pace made the process feel much easier. My written code answers became much more organized. The plan changed with my mock and homework results, so the work never felt random. Lesson times could fit around school, university or work. Thank you to the tutor who stayed supportive until the end.

    Jun Wei

  • LNAT

    Zhihao Wang

  • IGCSE / GCSE

    Having the lesson move at my pace made the process feel much easier. Over time, IGCSE Mathematics became one of the most organized parts of my IGCSE / GCSE preparation. I started noticing the reason for a mistake much faster. I was really happy with the lessons.

    Linh Nguyen

  • IELTS Academic

    We reduced the memorized phrases so my answers sounded more natural. The preparation felt calmer than I expected.

    Sneha Sandhu

  • PTE Academic

    Over time, Describe Image became one of the most organized parts of my PTE Academic preparation. Near the exam, it was clear what to keep doing and what to stop. It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. My preparation became much more regular and easier to track. My mock results gradually became more consistent. Thanks to TestPrep for helping me stay on track.

    Moritz Hoffmann

  • Digital SAT

    I was taking Advanced Math at school, but getting used to the exam questions took time. Lesson times could fit around school, university or work. Seeing several versions of the same topic made unfamiliar questions less stressful. Near the exam, it was clear what to keep doing and what to stop. We didn't spend extra time on things I already knew. Thanks to TestPrep for helping me stay on track.

    Andres Mercado

  • IB Diploma

    We didn't spend extra time on things I already knew. I finally understood what was going wrong in IB Chemistry. I found a better balance between regular school and exam preparation. I'm genuinely thankful to my tutor for being patient.
