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!

  • LNAT

    The feedback I received on Section B Essay was clear and practical. By the end of each lesson, I knew what I was supposed to do during the week. Discussing why the other choices were wrong helped more than I expected. There was no overnight miracle, but the progress was easy to see. I wasn't trying to learn new topics at the very last minute. Thank you to the tutor who stayed supportive until the end.

    Lauren Langley

  • LNAT

    Breaking Section B Essay into smaller pieces worked much better for me. I left the exam feeling that I had done what I could.

    Ilaria Caruso

  • LNAT

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

  • LNAT

    Online lessons made it possible to continue without losing time on travel. We were happy with both the teaching and the communication.

    Fabio Vieira

  • LNAT

    Lesson times could fit around school, university or work. Over time, Argument Analysis became one of the most organized parts of my LNAT preparation. My preparation became much more regular and easier to track. I was really happy with the lessons.

    Nuno Brito

  • LNAT

    Even in a group lesson, the tutor knew where each of us stood. Over time, Argument Analysis became one of the most organized parts of my LNAT preparation. I started noticing the reason for a mistake much faster. Thank you to the tutor who stayed supportive until the end.

    Flynn McGrath

  • LNAT

    Our child wasn't sure how to organize the preparation for LNAT. The tutor's calm approach helped protect motivation during the intensive period. Online lessons made it possible to continue without losing time on travel. Flexible scheduling helped during a demanding school year. We were happy with both the teaching and the communication.

    Orla Spencer

  • LNAT

    Over time, Reading Comprehension became one of the most organized parts of my LNAT preparation. I became much more comfortable asking questions in class.

    Imogen Tierney

  • LNAT

    Keeping up with LNAT while school was busy was harder than I expected. Thank you to my tutor and the TestPrep team.

    Arda Ucar

  • LNAT

    The class felt relaxed enough to ask questions without overthinking it. The feedback I received on Reading Comprehension was clear and practical. I started noticing the reason for a mistake much faster. The preparation felt calmer than I expected.

    Yuto Shimizu

  • LNAT

    Our child had a clear goal but no steady study routine. Seeing the change in our child made us very happy.

    Filippo Costa

  • LNAT

    The feedback I received on Section A MCQ was clear and practical. Discussing why the other choices were wrong helped more than I expected. After a while, the questions started to feel much more familiar.

    Mariana Urrutia

  • LNAT

    At the beginning, we knew very little about the LNAT system as parents. We were able to follow the mock results regularly. Seeing the change in our child made us very happy.

    Qianyu Lin

  • LNAT

    Breaking Section B Essay into smaller pieces worked much better for me. I went into the exam much calmer than I would have before.

    Akari Miura

  • LNAT

    We wanted our child to keep up with the school pace in Section A MCQ. Online lessons made it possible to continue without losing time on travel. We would recommend the program to students and families in a similar situation.

  • LNAT

    After my first attempt, I wanted the second round of preparation to feel more organized. I started noticing the reason for a mistake much faster.

    Jordan Jarvis

  • LNAT

    After each test, we looked beyond the score and reviewed the type of each mistake. I finally understood what was going wrong in Reading Comprehension. There was no overnight miracle, but the progress was easy to see. Thank you to the tutor who stayed supportive until the end.

    Nico Vos

  • LNAT

    I chose Argument Analysis this year and wanted to build a solid base from the beginning. I started noticing the reason for a mistake much faster.

    Carlotta Bianco

  • LNAT

    The LNAT format felt unnecessarily confusing at first. We didn't spend extra time on things I already knew. My mock results gradually became more consistent. It was an intense period, but it was worth it.

    Brooke Driscoll

  • 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

  • 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

  • LNAT

    Keeping up with LNAT while school was busy was harder than I expected. Breaking Reading Comprehension into smaller pieces worked much better for me. We could make the workload lighter during busy weeks at school or university. My written answers became shorter, clearer and easier to follow. Knowing what to study reduced a lot of the stress. The preparation felt calmer than I expected.

    Damian Ibarra

  • LNAT

    I was taking Reading Comprehension at school, but getting used to the exam questions took time. We didn't spend extra time on things I already knew. After a while, the questions started to feel much more familiar. Thank you to my tutor and the TestPrep team.

    Marissa Vaughn

  • LNAT

    When I started preparing for LNAT, I wasn't sure what order to study things in. We were realistic about what could be improved in the time available. My preparation became much more regular and easier to track. I'm genuinely thankful to my tutor for being patient.
