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!

  • SSAT

    After my first attempt, I wanted the second round of preparation to feel more organized. Lesson times could fit around school, university or work. After a while, the questions started to feel much more familiar. I'm glad I worked with my tutor through this process.

    Valentina Reinoso

  • TOEFL iBT

    Anxiety became more visible as the exam got closer. It was good to see confidence returning over time. We thank the tutor and the TestPrep team.

    Louis Aubert

  • AP Exams

    The AP Exams format felt unnecessarily confusing at first. After a while, the questions started to feel much more familiar.

    Pippa McLean

  • UCAT

    I wasn't starting from zero, but the same mistakes kept showing up in my mocks. I finally understood what was going wrong in Time Management. I started tracking the type of mistake, not just the number of questions I completed. Practicing in the real exam format made test day feel much less unfamiliar. I found a better balance between regular school and exam preparation. I'm glad I worked with my tutor through this process.

    Mariano Carranza

  • IGCSE / GCSE

    Breaking IGCSE History into smaller pieces worked much better for me. I stopped listing facts in essays and started building an actual argument. There was no overnight miracle, but the progress was easy to see.

    Josefina Paredes

  • UCAT

    What annoyed me most was losing easy points because I rushed. My tutor could see my reasoning and usually found the source of an error quickly. Discussing why the other choices were wrong helped more than I expected. My tutor usually asked me to explain my thinking before stepping in. We didn't spend extra time on things I already knew. The preparation felt calmer than I expected.

    Johanna Martens

  • IB Diploma

    Our daughter needed regular support with IB World History. It was good to see confidence returning over time.

    Huy Dang

  • Digital SAT

    Our daughter needed regular support with Problem Solving & Data Analysis. We were able to follow the mock results regularly.

    Mariana Branco

  • LSAT

    Over time, Reading Comprehension became one of the most organized parts of my LSAT preparation. Discussing why the other choices were wrong helped more than I expected. I started noticing the reason for a mistake much faster.

    Eliza Cormack

  • A-Level

    The feedback I received on A-Level Psychology was clear and practical. I started tracking the type of mistake, not just the number of questions I completed. Connecting examples back to the main point made my writing more consistent. Knowing what to study reduced a lot of the stress. I started noticing the reason for a mistake much faster. The preparation felt calmer than I expected.

    Ramiro Solis

  • SSAT

    The plan was adjusted when school exams became busy. We thank the tutor and the TestPrep team.

    Putri Nasution

  • IB Diploma

    What annoyed me most was losing easy points because I rushed. It was an intense period, but it was worth it.

    Ananya Bedi

  • IB Diploma

    I chose IB English A this year and wanted to build a solid base from the beginning. We could make the workload lighter during busy weeks at school or university. A lot of my mistakes came from rushing through the wording of the question. A big thank you to my tutor for all the support :)

    Wesley Hanley

  • GMAT Focus

    Over time, Verbal Reasoning became one of the most organized parts of my GMAT Focus preparation. I started tracking the type of mistake, not just the number of questions I completed. Discussing why the other choices were wrong helped more than I expected. My mock results gradually became more consistent. After a while, the questions started to feel much more familiar. Thank you to the tutor who stayed supportive until the end.

    Yuxin Fang

  • LNAT

    Breaking Section A MCQ into smaller pieces worked much better for me. The plan changed with my mock and homework results, so the work never felt random. I learned not to spend the same amount of time on every line of a long text. There was no overnight miracle, but the progress was easy to see. I went into the exam much calmer than I would have before. Thanks to everyone who supported me.

    Megan Burke

  • IB Diploma

    Practicing in the real exam format made test day feel much less unfamiliar. I was really happy with the lessons.

    Umut Kartal

  • Digital SAT

    Learning when to leave a hard question made a real difference to my timing. Thank you to the tutor who stayed supportive until the end.

    Lihua Wang

  • IELTS Academic

    The IELTS Academic format felt unnecessarily confusing at first. My tutor could see my reasoning and usually found the source of an error quickly. My preparation became much more regular and easier to track. Thanks to everyone who supported me.

    Sooyoung Nam

  • A-Level

    Keeping up with A-Level while school was busy was harder than I expected. After a while, the questions started to feel much more familiar.

    Chloe Nolan

  • AP Exams

    We weren't sure whether online lessons would be effective. Joining lessons willingly was one of the clearest signs for us. Communication with the team was straightforward and our questions were answered. Regular work on similar question types reduced repeated mistakes. Flexible scheduling helped during a demanding school year. Seeing the change in our child made us very happy.

    Aisling Chandler

  • LSAT

    I had collected too many resources without knowing when to use any of them. After a while, the questions started to feel much more familiar.

    Damien Gaudin

  • IB Diploma

    After my first attempt, I wanted the second round of preparation to feel more organized. I'm genuinely thankful to my tutor for being patient.

    Ece Aktas

  • IGCSE / GCSE

    I was doing questions for IGCSE Business Studies on my own but never had a steady routine. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. My case responses became more organized and direct. A big thank you to my tutor for all the support :)

    Dimas Halim

  • PTE Academic

    As the exam got closer, I wasn't sure what I should actually review. Full-length mocks helped me get used to the real exam pace. Predicting the output helped me catch small logic errors. I stopped doing a huge amount one week and nothing the next. Thank you to my tutor and the TestPrep team.
