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!

Student reviews

  • IGCSE / GCSE

    After the first attempt, we looked for a calmer plan for the retake. A good connection with the tutor developed quite quickly. We thank the tutor and the TestPrep team.

    Flynn Clarke

  • SSAT

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

    Johanna Meier

  • LNAT

    I chose Section A MCQ this year and wanted to build a solid base from the beginning. My preparation became much more regular and easier to track.

    Mason Sawyer

  • IGCSE / GCSE

    The feedback I received on IGCSE Turkish was clear and practical. I can now decide much faster when to move on from a question. I left the exam feeling that I had done what I could.

    Corentin Lemoine

  • Digital SAT

    Our son's school schedule was already very busy. Being able to fit lessons around school made the process easier. Preparation looked calmer and more organized closer to the exam. It was good to see confidence returning over time. We were happy with both the teaching and the communication.

    Trisha Saxena

  • A-Level

    Keeping up with A-Level while school was busy was harder than I expected. My tutor made it easy to ask questions from the first lesson. Having the lesson move at my pace made the process feel much easier. Connecting examples back to the main point made my writing more consistent. My preparation became much more regular and easier to track. I was really happy with the lessons.

    Rahul Iyer

  • A-Level

    Everyone recommended different resources and I kept switching between them. The mocks showed where my time was actually being lost. Knowing what to study reduced a lot of the stress. The preparation felt calmer than I expected.

    Rohan Shetty

  • AP Exams

    I was doing questions for AP European History on my own but never had a steady routine. I used the question bank regularly to return to weaker topics. 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. Thanks to everyone who supported me.

    Sienna Keating

  • LSAT

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

    Gonzalo Espinoza

  • Digital SAT

    I started seeing shorter solutions that were easier to check under time pressure. Thanks to TestPrep for helping me stay on track.

    Jack Connors

  • IGCSE / GCSE

    We didn't spend extra time on things I already knew. I finally understood what was going wrong in IGCSE Business Studies. My preparation became much more regular and easier to track. The preparation felt calmer than I expected.

    Flynn Finlay

  • TOEFL iBT

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

    Maja Richter

  • AP Exams

    I became much more careful with graphs, experiments and data-based questions. I'm genuinely thankful to my tutor for being patient.

    Milagros Ledesma

  • IB Diploma

    During the intensive review, we returned to real gaps instead of restarting everything. I finally understood what was going wrong in IB Visual Arts. There was no overnight miracle, but the progress was easy to see. A big thank you to my tutor for all the support :)

    Alba Loureiro

  • IGCSE / GCSE

    It was good to see confidence returning over time. Thank you sincerely to everyone involved.

    Morgan Warren

  • AP Exams

    I was close to my target, but my results changed a lot from one test to the next. Choosing questions by topic made my practice time much more useful. We focused more on understanding what the problem asked than memorizing formulas. I never felt awkward asking the same thing again. The preparation felt calmer than I expected.

    Lotte Thiele

  • IMAT

    Over time, Physics became one of the most organized parts of my IMAT preparation. After a while, the questions started to feel much more familiar.

    Rodrigo Braga

  • Digital SAT

    After my first attempt, I wanted the second round of preparation to feel more organized. I never felt awkward asking the same thing again. Having the lesson move at my pace made the process feel much easier. Seeing several versions of the same topic made unfamiliar questions less stressful. After a while, the questions started to feel much more familiar. I'm glad I worked with my tutor through this process.

    Zoe Keating

  • IB Diploma

    Our child had a clear goal but no steady study routine. Individual lesson time was used around our child's actual needs. The tutor supported regular study, not only the lesson content. Mistakes became something to work on rather than something to feel bad about. We thank the tutor and the TestPrep team.

    Chelsea McKenzie

  • IGCSE / GCSE

    We focused more on understanding what the problem asked than memorizing formulas. A big thank you to my tutor for all the support :)

    Martin Navarrete

  • IELTS Academic

    Our child had a clear goal but no steady study routine. Preparation looked calmer and more organized closer to the exam.

    Kerem Kurt

  • LSAT

    After my first attempt, I wanted a calmer and more focused plan for the retake. Choosing questions by topic made my practice time much more useful. I stopped choosing answers by feel and started looking for evidence in the passage. My tutor made it easy to ask questions from the first lesson. I used the question bank regularly to return to weaker topics. The preparation felt calmer than I expected.

    Ewan Nolan

  • IELTS Academic

    Keeping up with IELTS Academic while school was busy was harder than I expected. I'm genuinely thankful to my tutor for being patient.

    Connor Harcourt

  • GRE General

    I had been studying alone, but my results stopped improving after a point. Choosing questions by topic made my practice time much more useful. I started seeing shorter solutions that were easier to check under time pressure. Going back to the lesson recordings helped when I forgot a small step. After enough examples of the same question type, the repeated mistakes decreased. Thanks to TestPrep for helping me stay on track.
