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

    I stopped listing facts in essays and started building an actual argument. I'm glad I worked with my tutor through this process.

    Jiyeon Moon

  • A-Level

    Breaking A-Level Psychology into smaller pieces worked much better for me. Connecting examples back to the main point made my writing more consistent. My mock results gradually became more consistent.

    Kanya Boonmee

  • IGCSE / GCSE

    Past-paper questions showed me how different topics could appear together. The preparation felt calmer than I expected.

    Kaito Ishii

  • LSAT

    I knew my target, but I didn't have a realistic routine for LSAT. I became much more comfortable asking questions in class.

    Xiaoyu Shi

  • AP Exams

    Our son's school schedule was already very busy. We were happy with both the teaching and the communication.

    Harrison Underwood

  • IGCSE / GCSE

    I wasn't starting from zero, but the same mistakes kept showing up in my mocks. I wasn't trying to learn new topics at the very last minute.

    Alice Caldwell

  • UCAT

    I was taking Verbal Reasoning at school, but getting used to the exam questions took time. I stopped doing a huge amount one week and nothing the next. My written answers became shorter, clearer and easier to follow. Thank you to the tutor who stayed supportive until the end.

    Liam Walsh

  • IELTS Academic

    Lesson times could fit around school, university or work. The feedback I received on Writing Task 1 was clear and practical. After a while, the questions started to feel much more familiar. Thank you to my tutor and the TestPrep team.

    Manav Dhar

  • LSAT

    After my first attempt, I wanted a calmer and more focused plan for the retake. Near the exam, it was clear what to keep doing and what to stop. A clear plan for the final weeks made priorities much easier to see. I learned not to spend the same amount of time on every line of a long text. I found a better balance between regular school and exam preparation. Thank you to the tutor who stayed supportive until the end.

    Jordan Callahan

  • IB Diploma

    Keeping up with IB Diploma while school was busy was harder than I expected. I used the question bank regularly to return to weaker topics. Knowing the criteria from the start made the whole task less vague. I stopped doing a huge amount one week and nothing the next. Choosing questions by topic made my practice time much more useful. The preparation felt calmer than I expected.

    Morgan Hawkins

  • IB Diploma

    The tutor supported regular study, not only the lesson content. The overall experience was positive from beginning to end.

    Rita Leitao

  • IMAT

    I finally understood what was going wrong in Logical Reasoning. Knowing the topic wasn't always enough; I had to learn which information the question actually needed. After a while, the questions started to feel much more familiar.

    Alana Donovan

  • IGCSE / GCSE

    Keeping up with IGCSE / GCSE while school was busy was harder than I expected. I was really happy with the lessons.

    Maelle Girard

  • PTE Academic

    I came back to Describe Image after a long break and wasn't sure where to begin. Having the lesson move at my pace made the process feel much easier. I learned not to lose the rest of a listening task because I missed one word. One bad mock no longer made me want to drop the whole plan. Lesson times could fit around school, university or work. The preparation felt calmer than I expected.

    Can Bozkurt

  • PTE Academic

    Our child had a clear goal but no steady study routine. A good connection with the tutor developed quite quickly. The small group offered peer learning without making it hard to ask questions. It was good to see confidence returning over time. We quickly felt that the tutor was a good match.

    Fernanda Tellez

  • GMAT Focus

    Balancing GMAT Focus 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. Focusing on past papers and mock review worked well near the exam. Seeing several versions of the same topic made unfamiliar questions less stressful. I wasn't trying to learn new topics at the very last minute. It was an intense period, but it was worth it.

    Natsuki Harada

  • IB Diploma

    I wasn't starting from zero, but the same mistakes kept showing up in my mocks. Even in a group lesson, the tutor knew where each of us stood. Knowing the topic wasn't always enough; I had to learn which information the question actually needed. The plan changed with my mock and homework results, so the work never felt random. Questions from other students often helped me as well. A big thank you to my tutor for all the support :)

    Paula Baptista

  • AP Exams

    The AP Exams format felt unnecessarily confusing at first. I was really happy with the lessons.

    Rohan Jadhav

  • PTE Academic

    As the exam got closer, I wasn't sure what I should actually review. Going back to the lesson recordings helped when I forgot a small step. Questions from other students often helped me as well. We reduced the memorized phrases so my answers sounded more natural. I became much more comfortable asking questions in class. Thank you to my tutor and the TestPrep team.

    Alessio Giordano

  • LNAT

    Breaking Section A MCQ into smaller pieces worked much better for me. I wasn't trying to learn new topics at the very last minute.

    Ramon Salonga

  • Digital SAT

    We wanted our child to keep up with the school pace in Algebra. A good connection with the tutor developed quite quickly.

    Nolan Harrington

  • LNAT

    Our child had a clear goal but no steady study routine. Mistakes became something to work on rather than something to feel bad about. We quickly felt that the tutor was a good match.

    Caio Garcia

  • YÖS / TR-YÖS

    What annoyed me most was losing easy points because I rushed. The feedback I received on Time Management was clear and practical. We could make the workload lighter during busy weeks at school or university. Seeing several versions of the same topic made unfamiliar questions less stressful. Knowing what to study reduced a lot of the stress. I was really happy with the lessons.

    Jaehyun Oh

  • TOEFL iBT

    I learned not to lose the rest of a listening task because I missed one word. I was really happy with the lessons.
