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!

  • UCAT

    After the first attempt, we looked for a calmer plan for the retake. Preparation looked calmer and more organized closer to the exam.

    Cole Montgomery

  • UCAT

    When I started preparing for UCAT, I wasn't sure what order to study things in. Breaking Time Management into smaller pieces worked much better for me. We could make the workload lighter during busy weeks at school or university. Sorting mistakes after each mock changed the way I studied. Knowing what to study reduced a lot of the stress. Thanks to everyone who supported me.

    Henrique Ramos

  • UCAT

    I chose Verbal Reasoning this year and wanted to build a solid base from the beginning. My tutor usually asked me to explain my thinking before stepping in. Lesson times could fit around school, university or work. A lot of my mistakes came from rushing through the wording of the question. My mock results gradually became more consistent. I'm glad I worked with my tutor through this process.

    Federico Sala

  • UCAT

    Our child wasn't sure how to organize the preparation for UCAT. The tutor's close attention to weaker areas gave us confidence. We quickly felt that the tutor was a good match.

    Andres Benitez

  • UCAT

    Keeping up with UCAT while school was busy was harder than I expected. Full-length mocks helped me get used to the real exam pace. Seeing several versions of the same topic made unfamiliar questions less stressful. I never felt awkward asking the same thing again. Experiencing the exam format beforehand made test day much less stressful. It was an intense period, but it was worth it.

    Devin Prescott

  • UCAT

    Our daughter needed regular support with Verbal Reasoning. A good connection with the tutor developed quite quickly.

    Reagan Ramsey

  • UCAT

    Breaking Situational Judgement into smaller pieces worked much better for me. My tutor usually asked me to explain my thinking before stepping in. I can now decide much faster when to move on from a question. Knowing what to study reduced a lot of the stress. My confidence improved along with the results. I was really happy with the lessons.

    Misaki Maeda

  • UCAT

    Keeping up with UCAT while school was busy was harder than I expected. Over time, Quantitative Reasoning became one of the most organized parts of my UCAT preparation. By the end of each lesson, I knew what I was supposed to do during the week. I started seeing shorter solutions that were easier to check under time pressure. I wasn't trying to learn new topics at the very last minute. The preparation felt calmer than I expected.

    Rodrigo Montoya

  • UCAT

    I was doing questions for Quantitative Reasoning on my own but never had a steady routine. Even in a group lesson, the tutor knew where each of us stood. I became much more comfortable asking questions in class. Thank you to the tutor who stayed supportive until the end.

    Itsuki Ota

  • UCAT

    I was doing questions for Time Management on my own but never had a steady routine. A big thank you to my tutor for all the support :)

    Romina Chacon

  • UCAT

    After my first attempt, I wanted the second round of preparation to feel more organized. My preparation became much more regular and easier to track.

    Nuno Rojas

  • UCAT

    I finally understood what was going wrong in Time Management. Sorting mistakes after each mock changed the way I studied. Knowing what to study reduced a lot of the stress.

    Grant Donovan

  • UCAT

    I chose Verbal Reasoning this year and wanted to build a solid base from the beginning. Over time, Verbal Reasoning became one of the most organized parts of my UCAT preparation. I stopped doing a huge amount one week and nothing the next. Discussing why the other choices were wrong helped more than I expected. I went into the exam much calmer than I would have before. Thank you to my tutor and the TestPrep team.

    Ruben Cabrera

  • UCAT

    After my first attempt, I wanted the second round of preparation to feel more organized. Lesson times could fit around school, university or work. There was no overnight miracle, but the progress was easy to see. I'm genuinely thankful to my tutor for being patient.

    Esteban Reinoso

  • UCAT

    I can now decide much faster when to move on from a question. I'm genuinely thankful to my tutor for being patient.

    Marek Norberg

  • 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

  • UCAT

    Our child wasn't sure how to organize the preparation for UCAT. It was good to see confidence returning over time.

    Sujin Min

  • UCAT

    Mistakes became something to work on rather than something to feel bad about. Preparation looked calmer and more organized closer to the exam. The overall experience was positive from beginning to end.
