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

    I wasn't starting from zero, but the same mistakes kept showing up in my mocks. I started tracking the type of mistake, not just the number of questions I completed. Questions from other students often helped me as well. The writing feedback helped me stop repeating the same sentence-level errors. Knowing what to study reduced a lot of the stress. It was an intense period, but it was worth it.

    Noelia Montalvo

  • PTE Academic

    I knew my target, but I didn't have a realistic routine for PTE Academic. Having the lesson move at my pace made the process feel much easier. It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. My tutor usually asked me to explain my thinking before stepping in. Lesson times could fit around school, university or work. I'm glad I worked with my tutor through this process.

    Ishita Banerjee

  • PTE Academic

    We didn't spend extra time on things I already knew. Breaking Reading into smaller pieces worked much better for me. There was no overnight miracle, but the progress was easy to see. I'm glad I worked with my tutor through this process.

    Mariel Tolentino

  • PTE Academic

    I had been studying alone, but my results stopped improving after a point. The class felt relaxed enough to ask questions without overthinking it. I left the exam feeling that I had done what I could. Thanks to TestPrep for helping me stay on track.

    Harper Connelly

  • PTE Academic

    Communication with the team was straightforward and our questions were answered. The overall experience was positive from beginning to end.

    Pranav Kulkarni

  • PTE Academic

    Our daughter needed regular support with Computer-Based Practice. It was good to see confidence returning over time. We would recommend the program to students and families in a similar situation.

    Bonnie Harrison

  • PTE Academic

    The feedback I received on Listening was clear and practical. I found a better balance between regular school and exam preparation.

    Wesley Merritt

  • PTE Academic

    I was close to my target, but my results changed a lot from one test to the next. My tutor made it easy to ask questions from the first lesson. Lesson times could fit around school, university or work. I developed a clearer way to return to the text during reading questions. I became much more comfortable asking questions in class. Thanks to everyone who supported me.

    Saskia Richter

  • PTE Academic

    Joining lessons willingly was one of the clearest signs for us. A good connection with the tutor developed quite quickly. Thank you sincerely to everyone involved.

    Arianna Palmieri

  • PTE Academic

    Our child wasn't sure how to organize the preparation for PTE Academic. Preparation looked calmer and more organized closer to the exam. Mistakes became something to work on rather than something to feel bad about. Being able to fit lessons around school made the process easier. The lessons started being followed without constant reminders from us. We quickly felt that the tutor was a good match.

    Callum Webster

  • PTE Academic

    The PTE Academic format felt unnecessarily confusing at first. Having the lesson move at my pace made the process feel much easier. I learned not to lose the rest of a listening task because I missed one word. I started tracking the type of mistake, not just the number of questions I completed. Lesson times could fit around school, university or work. I was really happy with the lessons.

    Skye Ingram

  • PTE Academic

    I was taking Computer-Based Practice at school, but getting used to the exam questions took time. By the end of each lesson, I knew what I was supposed to do during the week. Before coding, I began thinking about which structure actually fit the problem. I was really happy with the lessons.

    Delaney McAllister

  • 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. It was an intense period, but it was worth it.

    Austin Delaney

  • PTE Academic

    Keeping up with PTE Academic while school was busy was harder than I expected. Thank you to the tutor who stayed supportive until the end.

    Abril Arriaga

  • PTE Academic

    We reduced the memorized phrases so my answers sounded more natural. Thank you to my tutor and the TestPrep team.

    Holly Harrison

  • PTE Academic

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

    Karina Benes

  • PTE Academic

    Mistakes became something to work on rather than something to feel bad about. We thank the tutor and the TestPrep team.

    Taeho Oh

  • PTE Academic

    Balancing PTE Academic preparation with university and work was harder than I expected. I'm genuinely thankful to my tutor for being patient.

    Camila Galindo

  • PTE Academic

    Over time, Repeat Sentence became one of the most organized parts of my PTE Academic preparation. I learned not to lose the rest of a listening task because I missed one word. After a while, the questions started to feel much more familiar.

    Hao Liu

  • PTE Academic

    I chose Listening this year and wanted to build a solid base from the beginning. 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. Thanks to TestPrep for helping me stay on track.

    Kenji Miura

  • PTE Academic

    The feedback I received on Reading was clear and practical. I found a better balance between regular school and exam preparation.

    Renata Escobar

  • PTE Academic

    I came back to Write from Dictation after a long break and wasn't sure where to begin. It was an intense period, but it was worth it.

    Oliver Sweeney

  • PTE Academic

    A clear plan for the final weeks made priorities much easier to see. The feedback I received on Speaking & Writing was clear and practical. I started noticing the reason for a mistake much faster. A big thank you to my tutor for all the support :)

    Nathan Bennett

  • PTE Academic

    We didn't spend extra time on things I already knew. Breaking Computer-Based Practice into smaller pieces worked much better for me. My mock results gradually became more consistent. Thank you to my tutor and the TestPrep team.
