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!

  • SSAT

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

    Lucia Fuentes

  • SSAT

    I chose Middle Level this year and wanted to build a solid base from the beginning. The plan changed with my mock and homework results, so the work never felt random. The group never had more than six students, so it was easy to stay involved. Timed work showed exactly which section was slowing me down. I went into the exam much calmer than I would have before. I'm glad I worked with my tutor through this process.

    Remi Benoit

  • SSAT

    The feedback I received on Verbal was clear and practical. I started noticing the reason for a mistake much faster.

    Imogen Ridley

  • SSAT

    Keeping up with SSAT while school was busy was harder than I expected. I used the question bank regularly to return to weaker topics. My confidence improved along with the results. Thank you to my tutor and the TestPrep team.

    Mitchell Corbett

  • SSAT

    I finally understood what was going wrong in Elementary Level. Timed work showed exactly which section was slowing me down. I wasn't trying to learn new topics at the very last minute.

    Nayeon Guk

  • SSAT

    I was close to my target, but my results changed a lot from one test to the next. My preparation became much more regular and easier to track.

    Hamish OBrien

  • SSAT

    Everyone recommended different resources and I kept switching between them. Near the exam, it was clear what to keep doing and what to stop. I learned not to spend the same amount of time on every line of a long text. The preparation felt calmer than I expected.

    Bianca Miranda

  • SSAT

    I was taking Verbal at school, but getting used to the exam questions took time. Lesson times could fit around school, university or work. I learned not to spend the same amount of time on every line of a long text. I stopped doing a huge amount one week and nothing the next. Having the lesson move at my pace made the process feel much easier. Thanks to TestPrep for helping me stay on track.

    Jordan Ridley

  • SSAT

    Over time, Middle Level became one of the most organized parts of my SSAT preparation. Knowing what to study reduced a lot of the stress.

    Zihan Zhao

  • SSAT

    I was doing questions for Quantitative on my own but never had a steady routine. I'm glad I worked with my tutor through this process.

    Peng Tang

  • SSAT

    Breaking Writing Sample into smaller pieces worked much better for me. My written answers became shorter, clearer and easier to follow. I left the exam feeling that I had done what I could.

    Luana Gomes

  • SSAT

    After my first attempt, I wanted the second round of preparation to feel more organized. Lesson times could fit around school, university or work. Timed work showed exactly which section was slowing me down. I stopped doing a huge amount one week and nothing the next. We didn't spend extra time on things I already knew. I'm glad I worked with my tutor through this process.

    Bjorn Novak

  • SSAT

    As the exam got closer, I wasn't sure what I should actually review. One bad mock no longer made me want to drop the whole plan. Timed work showed exactly which section was slowing me down. I was really happy with the lessons.

    Erin Finlay

  • SSAT

    After the first attempt, we looked for a calmer plan for the retake. Seeing the change in our child made us very happy.

    Sergio Caldeira

  • SSAT

    After my first attempt, I wanted the second round of preparation to feel more organized. Lesson times could fit around school, university or work. After a while, the questions started to feel much more familiar. I'm glad I worked with my tutor through this process.

    Valentina Reinoso

  • SSAT

    The plan was adjusted when school exams became busy. We thank the tutor and the TestPrep team.

    Putri Nasution

  • SSAT

    Lesson times could fit around school, university or work. Breaking Writing Sample into smaller pieces worked much better for me. After a while, the questions started to feel much more familiar. Thanks to TestPrep for helping me stay on track.

    Juliana Santos

  • SSAT

    Breaking Quantitative into smaller pieces worked much better for me. I never felt awkward asking the same thing again. We focused more on understanding what the problem asked than memorizing formulas. I became much more comfortable asking questions in class. My confidence improved along with the results. Thanks to TestPrep for helping me stay on track.

    Gonzalo Guerreiro

  • SSAT

    I was close to my target, but my results changed a lot from one test to the next. Experiencing the exam format beforehand made test day much less stressful. I found a better balance between regular school and exam preparation. I was really happy with the lessons.

    Kabir Anand

  • SSAT

    Our child had a clear goal but no steady study routine. A good connection with the tutor developed quite quickly. Individual lesson time was used around our child's actual needs. We were able to follow the mock results regularly. Joining lessons willingly was one of the clearest signs for us. We were pleased with the support we received.

    Irene Guerreiro

  • SSAT

    Lesson times could fit around school, university or work. Over time, Upper Level became one of the most organized parts of my SSAT preparation. My mock results gradually became more consistent. It was an intense period, but it was worth it.

    Brooke Langford

  • SSAT

    The feedback I received on Reading was clear and practical. A lot of my mistakes came from rushing through the wording of the question. My confidence improved along with the results.

    Miguel Campos

  • SSAT

    I was taking Elementary Level 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. The mocks showed where my time was actually being lost. Sorting mistakes after each mock changed the way I studied. My confidence improved along with the results. I'm glad I worked with my tutor through this process.

    Rohit Jadhav

  • SSAT

    Everyone recommended different resources and I kept switching between them. Even in a group lesson, the tutor knew where each of us stood. After a while, the questions started to feel much more familiar. It was an intense period, but it was worth it.
