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!

  • IB Diploma

    I finally understood what was going wrong in IB Geography. My preparation became much more regular and easier to track.

    Brooklyn Whitman

  • ACT

    Our daughter needed regular support with ACT Reading. Individual lesson time was used around our child's actual needs. A good connection with the tutor developed quite quickly. We were able to follow the mock results regularly. Thank you sincerely to everyone involved.

    Luana Duarte

  • AP Exams

    At the beginning, we knew very little about the AP Exams system as parents. The tutor's close attention to weaker areas gave us confidence. We quickly felt that the tutor was a good match.

    Lucia Sequeira

  • AP Exams

    Anxiety became more visible as the exam got closer. Being able to fit lessons around school made the process easier. We would recommend the program to students and families in a similar situation.

    Duarte Pires

  • IELTS Academic

    Over time, Academic Reading became one of the most organized parts of my IELTS Academic preparation. One bad mock no longer made me want to drop the whole plan. The writing feedback helped me stop repeating the same sentence-level errors. I started noticing the reason for a mistake much faster. I went into the exam much calmer than I would have before. I was really happy with the lessons.

    Kyungsoo Moon

  • IB Diploma

    Even in a group lesson, the tutor knew where each of us stood. Over time, IB Global Politics became one of the most organized parts of my IB Diploma preparation. I left the exam feeling that I had done what I could. Thank you to my tutor and the TestPrep team.

    Dewi Hidayat

  • IMAT

    Anxiety became more visible as the exam got closer. The tutor's close attention to weaker areas gave us confidence. We thank the tutor and the TestPrep team.

    Josefina Tapia

  • Digital SAT

    I was taking SAT Math at school, but getting used to the exam questions took time. Questions from other students often helped me as well. I started seeing shorter solutions that were easier to check under time pressure. The plan changed with my mock and homework results, so the work never felt random. The class felt relaxed enough to ask questions without overthinking it. Thank you to my tutor and the TestPrep team.

    Jingyi Fu

  • AP Exams

    What annoyed me most was losing easy points because I rushed. I went into the exam much calmer than I would have before.

    Bianca Donati

  • SSAT

    I wasn't starting from zero, but the same mistakes kept showing up in my mocks. Breaking Upper Level into smaller pieces worked much better for me. By the end of each lesson, I knew what I was supposed to do during the week. Timed work showed exactly which section was slowing me down. I left the exam feeling that I had done what I could. The preparation felt calmer than I expected.

    Bastien Gauthier

  • A-Level

    I wasn't starting from zero, but the same mistakes kept showing up in my mocks. Going back to the lesson recordings helped when I forgot a small step. A clear plan for the final weeks made priorities much easier to see. Reviewing my work against the criteria changed the way I edited it. I went into the exam much calmer than I would have before. Thanks to TestPrep for helping me stay on track.

    Kai Jin

  • IGCSE / GCSE

    When I started preparing for IGCSE / GCSE, I wasn't sure what order to study things in. The group never had more than six students, so it was easy to stay involved. I learned to make a short plan before starting a long response. We could make the workload lighter during busy weeks at school or university. Even in a group lesson, the tutor knew where each of us stood. I was really happy with the lessons.

    Cooper Gibson

  • AP Exams

    After my first attempt, I wanted the second round of preparation to feel more organized. The class felt relaxed enough to ask questions without overthinking it. I went into the exam much calmer than I would have before. I'm genuinely thankful to my tutor for being patient.

    Mariana Arce

  • YÖS / TR-YÖS

    I was close to my target, but my results changed a lot from one test to the next. Thank you to the tutor who stayed supportive until the end.

    Finn Krause

  • AP Exams

    Breaking AP Physics 1 into smaller pieces worked much better for me. I went into the exam much calmer than I would have before.

    Catalina Villalba

  • A-Level

    As the exam got closer, I wasn't sure what I should actually review. Over time, A-Level History became one of the most organized parts of my A-Level preparation. The plan changed with my mock and homework results, so the work never felt random. Using the mark scheme to review my own answer was surprisingly helpful. After a while, the questions started to feel much more familiar. Thanks to everyone who supported me.

    Poppy Hargreaves

  • Digital SAT

    When I started preparing for Digital SAT, I wasn't sure what order to study things in. Breaking Craft & Structure into smaller pieces worked much better for me. My tutor usually asked me to explain my thinking before stepping in. Timed work showed exactly which section was slowing me down. I wasn't trying to learn new topics at the very last minute. Thanks to everyone who supported me.

    Romain Rolland

  • IB Diploma

    Breaking IB English A into smaller pieces worked much better for me. Near the exam, it was clear what to keep doing and what to stop. Discussing why the other choices were wrong helped more than I expected. There was no overnight miracle, but the progress was easy to see. My confidence improved along with the results. Thanks to TestPrep for helping me stay on track.

    Adrian Reyes

  • A-Level

    As the exam got closer, I wasn't sure what I should actually review. We balanced current school topics with past-paper practice. After a while, the questions started to feel much more familiar. It was an intense period, but it was worth it.

    Thao Ngo

  • UCAT

    I was doing questions for Time Management on my own but never had a steady routine. We could make the workload lighter during busy weeks at school or university. Sorting mistakes after each mock changed the way I studied. A big thank you to my tutor for all the support :)

    Filippo Gatti

  • AP Exams

    After my first attempt, I wanted the second round of preparation to feel more organized. Over time, AP Physics C: Mechanics became one of the most organized parts of my AP Exams preparation. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Knowing the topic wasn't always enough; I had to learn which information the question actually needed. I wasn't trying to learn new topics at the very last minute. I'm genuinely thankful to my tutor for being patient.

    Lara Peters

  • GRE General

    Balancing GRE General preparation with university and work was harder than I expected. My mock results gradually became more consistent.

    Akash Suri

  • GRE General

    Over time, Quantitative Reasoning became one of the most organized parts of my GRE General preparation. A quick check after each answer helped me catch small mistakes. My mock results gradually became more consistent.

    Paige Prescott

  • A-Level

    Lesson times could fit around school, university or work. Breaking A-Level English Literature into smaller pieces worked much better for me. I found a better balance between regular school and exam preparation. Thanks to TestPrep for helping me stay on track.
