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!

  • PTE Academic

    After my first attempt, I wanted the second round of preparation to feel more organized. Thank you to the tutor who stayed supportive until the end.

    Pauline Gerard

  • PTE Academic

    I came back to Reading after a long break and wasn't sure where to begin. The preparation felt calmer than I expected.

    Eduardo Nascimento

  • PTE Academic

    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. The class felt relaxed enough to ask questions without overthinking it. The writing feedback helped me stop repeating the same sentence-level errors. I wasn't trying to learn new topics at the very last minute. It was an intense period, but it was worth it.

    Giulio Palmieri

  • PTE Academic

    I was taking Listening at school, but getting used to the exam questions took time. Over time, Listening became one of the most organized parts of my PTE Academic preparation. Near the exam, it was clear what to keep doing and what to stop. I learned not to lose the rest of a listening task because I missed one word. There was no overnight miracle, but the progress was easy to see. Thanks to everyone who supported me.

    Oliver Atkins

  • PTE Academic

    What annoyed me most was losing easy points because I rushed. My tutor usually asked me to explain my thinking before stepping in. The group never had more than six students, so it was easy to stay involved. I started tracing code line by line instead of only reading it quickly. There was no overnight miracle, but the progress was easy to see. Thank you to my tutor and the TestPrep team.

    Aoi Nakajima

  • PTE Academic

    Over time, Describe Image became one of the most organized parts of my PTE Academic preparation. Near the exam, it was clear what to keep doing and what to stop. It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. My preparation became much more regular and easier to track. My mock results gradually became more consistent. Thanks to TestPrep for helping me stay on track.

    Moritz Hoffmann

  • PTE Academic

    We wanted our child to keep up with the school pace in Repeat Sentence. Communication with the team was straightforward and our questions were answered. The overall experience was positive from beginning to end.

    Facundo Arriaga

  • 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.

    Elke Meier

  • PTE Academic

    The feedback I received on Write from Dictation was clear and practical. We reduced the memorized phrases so my answers sounded more natural. My confidence improved along with the results.

    Zoe Lawson

  • PTE Academic

    The feedback I received on Write from Dictation was clear and practical. I never felt awkward asking the same thing again. It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. There was no overnight miracle, but the progress was easy to see. A big thank you to my tutor for all the support :)

    Lucy Hayes

  • PTE Academic

    Over time, Describe Image became one of the most organized parts of my PTE Academic preparation. I developed a clearer way to return to the text during reading questions. I wasn't trying to learn new topics at the very last minute.

    Leon Koch

  • PTE Academic

    Having the lesson move at my pace made the process feel much easier. I finally understood what was going wrong in Describe Image. I started noticing the reason for a mistake much faster. Thanks to everyone who supported me.

    Ruoxi Chen

  • PTE Academic

    I was doing questions for Speaking & Writing on my own but never had a steady routine. Lesson times could fit around school, university or work. I went into the exam much calmer than I would have before. I was really happy with the lessons.

    Bonnie Gibson

  • PTE Academic

    I was taking Reading at school, but getting used to the exam questions took time. The plan changed with my mock and homework results, so the work never felt random. Questions from other students often helped me as well. It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. I started noticing the reason for a mistake much faster. Thanks to everyone who supported me.

    Trevor Preston

  • PTE Academic

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

    Cooper Elliott

  • PTE Academic

    After the first attempt, we looked for a calmer plan for the retake. Being able to fit lessons around school made the process easier. We were pleased with the support we received.

    Ngoc Nguyen

  • PTE Academic

    I was doing questions for Listening on my own but never had a steady routine. Breaking Listening into smaller pieces worked much better for me. I stopped doing a huge amount one week and nothing the next. It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. I went into the exam much calmer than I would have before. I'm glad I worked with my tutor through this process.

    Haoran Guo

  • PTE Academic

    Our child wasn't sure how to organize the preparation for PTE Academic. Seeing the change in our child made us very happy.

    James Gallagher

  • PTE Academic

    I wasn't starting from zero, but the same mistakes kept showing up in my mocks. By the end of each lesson, I knew what I was supposed to do during the week. The writing feedback helped me stop repeating the same sentence-level errors. A big thank you to my tutor for all the support :)

    Ruby Gibson

  • PTE Academic

    I came back to Computer-Based Practice after a long break and wasn't sure where to begin. Thank you to the tutor who stayed supportive until the end.

    Simone Gatti

  • PTE Academic

    I had collected too many resources without knowing when to use any of them. The preparation felt calmer than I expected.

    Taemin Kang

    Carla Navarro

  • PTE Academic

    Breaking Computer-Based Practice into smaller pieces worked much better for me. Near the exam, it was clear what to keep doing and what to stop. Before coding, I began thinking about which structure actually fit the problem. I became much more comfortable asking questions in class. I left the exam feeling that I had done what I could. I'm genuinely thankful to my tutor for being patient.

    Adrien Lacroix

  • PTE Academic

    I was taking Computer-Based Practice at school, but getting used to the exam questions took time. We could make the workload lighter during busy weeks at school or university. After each test, we looked beyond the score and reviewed the type of each mistake. Predicting the output helped me catch small logic errors. I found a better balance between regular school and exam preparation. I was really happy with the lessons.
