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!

  • IELTS Academic

    I chose Writing Task 1 this year and wanted to build a solid base from the beginning. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Experiencing the exam format beforehand made test day much less stressful. We reduced the memorized phrases so my answers sounded more natural. After a while, the questions started to feel much more familiar. The preparation felt calmer than I expected.

    Tessa Brennan

  • IELTS Academic

    As the exam got closer, I wasn't sure what I should actually review. There was no overnight miracle, but the progress was easy to see.

    Sebastian Olvera

  • IELTS Academic

    Balancing IELTS Academic preparation with university and work was harder than I expected. Even in a group lesson, the tutor knew where each of us stood. We reduced the memorized phrases so my answers sounded more natural. Going back to the lesson recordings helped when I forgot a small step. The class felt relaxed enough to ask questions without overthinking it. A big thank you to my tutor for all the support :)

    Ivana Bergman

  • IELTS Academic

    My mock scores were inconsistent, so it was hard to judge my actual level. The feedback I received on Writing Task 1 was clear and practical. My tutor made it easy to ask questions from the first lesson. I developed a clearer way to return to the text during reading questions. I started noticing the reason for a mistake much faster. The preparation felt calmer than I expected.

    Rafael Leite

  • IELTS Academic

    When I started preparing for IELTS Academic, I wasn't sure what order to study things in. Thank you to my tutor and the TestPrep team.

    Shelby Winslow

  • IELTS Academic

    Balancing IELTS Academic preparation with university and work was harder than I expected. Over time, Writing Task 2 became one of the most organized parts of my IELTS 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. It was an intense period, but it was worth it.

    Natalia Quiroga

  • IELTS Academic

    Over time, Academic Reading became one of the most organized parts of my IELTS Academic preparation. I started tracking the type of mistake, not just the number of questions I completed. The writing feedback helped me stop repeating the same sentence-level errors. My confidence improved along with the results. I left the exam feeling that I had done what I could. It was an intense period, but it was worth it.

    Henrique Garcia

  • IELTS Academic

    In Academic Reading, timing was costing me more points than the content itself. We didn't spend extra time on things I already knew. I learned not to lose the rest of a listening task because I missed one word. Near the exam, it was clear what to keep doing and what to stop. Having the lesson move at my pace made the process feel much easier. Thanks to TestPrep for helping me stay on track.

    Dylan Goodwin

  • IELTS Academic

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

    Harriet Warren

  • IELTS Academic

    Breaking Writing Task 1 into smaller pieces worked much better for me. We reduced the memorized phrases so my answers sounded more natural. There was no overnight miracle, but the progress was easy to see.

    Greta Janssen

  • IELTS Academic

    Questions from other students often helped me as well. I finally understood what was going wrong in Writing Task 2. My mock results gradually became more consistent. I was really happy with the lessons.

    Paula Pires

  • IELTS Academic

    I developed a clearer way to return to the text during reading questions. Thanks to everyone who supported me.

    Nathan McLean

  • IELTS Academic

    The feedback I received on Speaking was clear and practical. It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. After a while, the questions started to feel much more familiar.

    Sungmin Yang

  • IELTS Academic

    After the first attempt, we looked for a calmer plan for the retake. A good connection with the tutor developed quite quickly. It was good to see confidence returning over time. The tutor's close attention to weaker areas gave us confidence. Mistakes became something to work on rather than something to feel bad about. The overall experience was positive from beginning to end.

    Adrian Pires

  • IELTS Academic

    We wanted our child to keep up with the school pace in Listening. The plan was adjusted when school exams became busy. The class size kept our child from disappearing into the background. Communication with the team was straightforward and our questions were answered. Online lessons made it possible to continue without losing time on travel. We quickly felt that the tutor was a good match.

    Stefano Marino

  • IELTS Academic

    After my first attempt, I wanted a calmer and more focused plan for the retake. We didn't spend extra time on things I already knew. I wasn't trying to learn new topics at the very last minute. Thank you to the tutor who stayed supportive until the end.

    Brooke Daley

  • IELTS Academic

    The feedback I received on Writing Task 1 was clear and practical. By the end of each lesson, I knew what I was supposed to do during the week. It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. After a while, the questions started to feel much more familiar. My mock results gradually became more consistent. Thank you to my tutor and the TestPrep team.

    Jisoo Ryu

  • IELTS Academic

    At the beginning, we knew very little about the IELTS Academic system as parents. Individual lesson time was used around our child's actual needs. We were happy with both the teaching and the communication.

    Lauren Gardner

  • IELTS Academic

    My mock scores were inconsistent, so it was hard to judge my actual level. One bad mock no longer made me want to drop the whole plan. I learned not to lose the rest of a listening task because I missed one word. Thank you to my tutor and the TestPrep team.

    Florencia Mendoza

  • IELTS Academic

    What annoyed me most was losing easy points because I rushed. Going back to the lesson recordings helped when I forgot a small step. I developed a clearer way to return to the text during reading questions. A big thank you to my tutor for all the support :)

    Pavel Dvorak

  • IELTS Academic

    After my first attempt, I wanted a calmer and more focused plan for the retake. The preparation felt calmer than I expected.

    Romina Zuniga

  • IELTS Academic

    The IELTS Academic format felt unnecessarily confusing at first. I finally understood what was going wrong in Academic Reading. By the end of each lesson, I knew what I was supposed to do during the week. 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. I was really happy with the lessons.
