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!

  • TOEFL iBT

    At the beginning, we knew very little about the TOEFL iBT system as parents. Flexible scheduling helped during a demanding school year. Thank you sincerely to everyone involved.

    Sungmin Kim

  • TOEFL iBT

    I had been studying alone, but my results stopped improving after a point. After a while, the questions started to feel much more familiar.

    Joel Jenkins

  • TOEFL iBT

    The feedback I received on Reading was clear and practical. It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. I found a better balance between regular school and exam preparation.

    Declan Langley

  • TOEFL iBT

    We noticed that the resources kept changing during independent study. The class size kept our child from disappearing into the background. We quickly felt that the tutor was a good match.

    Tanvi Banerjee

  • TOEFL iBT

    Everyone recommended different resources and I kept switching between them. I finally understood what was going wrong in Integrated Tasks. I never felt awkward asking the same thing again. I learned not to lose the rest of a listening task because I missed one word. I started noticing the reason for a mistake much faster. I was really happy with the lessons.

    Bonnie Lockwood

  • TOEFL iBT

    Breaking Speaking into smaller pieces worked much better for me. The writing feedback helped me stop repeating the same sentence-level errors. I went into the exam much calmer than I would have before.

    Hyunwoo Cho

  • TOEFL iBT

    Over time, Speaking became one of the most organized parts of my TOEFL iBT preparation. I learned not to lose the rest of a listening task because I missed one word. Knowing what to study reduced a lot of the stress.

    Liam Kirkwood

  • TOEFL iBT

    It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. Thanks to TestPrep for helping me stay on track.

    Cooper Harcourt

  • TOEFL iBT

    I finally understood what was going wrong in Reading. I developed a clearer way to return to the text during reading questions. There was no overnight miracle, but the progress was easy to see.

    Carolina Vieira

  • TOEFL iBT

    We wanted our child to keep up with the school pace in Speaking. Individual lesson time was used around our child's actual needs. We were happy with both the teaching and the communication.

    Leandro Villalba

  • TOEFL iBT

    I learned not to lose the rest of a listening task because I missed one word. I was really happy with the lessons.

    Marleen Krause

  • TOEFL iBT

    I knew my target, but I didn't have a realistic routine for TOEFL iBT. A big thank you to my tutor for all the support :)

    Bruno Nunes

  • TOEFL iBT

    Lesson times could fit around school, university or work. Breaking Integrated Tasks into smaller pieces worked much better for me. My preparation became much more regular and easier to track. Thank you to the tutor who stayed supportive until the end.

    Jonas Schafer

  • TOEFL iBT

    What annoyed me most was losing easy points because I rushed. My tutor made it easy to ask questions from the first lesson. Lesson times could fit around school, university or work. I learned not to lose the rest of a listening task because I missed one word. I went into the exam much calmer than I would have before. I'm genuinely thankful to my tutor for being patient.
