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

    Our child had a clear goal but no steady study routine. Individual lesson time was used around our child's actual needs. A good connection with the tutor developed quite quickly. The plan was adjusted when school exams became busy. We were happy with both the teaching and the communication.

    Cristian Ponce

  • SSAT

    When I started preparing for SSAT, I wasn't sure what order to study things in. It was an intense period, but it was worth it.

    Pinar Duman

  • SSAT

    Our child wasn't sure how to organize the preparation for SSAT. The small group offered peer learning without making it hard to ask questions. Mistakes became something to work on rather than something to feel bad about. Preparation looked calmer and more organized closer to the exam. We would recommend the program to students and families in a similar situation.

    Bailey Kirk

  • SSAT

    The SSAT format felt unnecessarily confusing at first. There was no overnight miracle, but the progress was easy to see.

    Yerin Jin

  • SSAT

    We wanted our child to keep up with the school pace in Upper Level. Thank you sincerely to everyone involved.

    Tahlia Newell

  • SSAT

    The SSAT format felt unnecessarily confusing at first. Near the exam, it was clear what to keep doing and what to stop. The mocks showed where my time was actually being lost. I learned not to spend the same amount of time on every line of a long text. My preparation became much more regular and easier to track. A big thank you to my tutor for all the support :)

    Emilia Farfan

  • SSAT

    Our child wasn't sure how to organize the preparation for SSAT. We would recommend the program to students and families in a similar situation.

    Mariel Soriano

  • SSAT

    The feedback I received on Middle Level was clear and practical. I can now decide much faster when to move on from a question. I started noticing the reason for a mistake much faster.

    Tianyu Su

  • SSAT

    I wasn't starting from zero, but the same mistakes kept showing up in my mocks. Having the lesson move at my pace made the process feel much easier. I learned not to spend the same amount of time on every line of a long text. Near the exam, it was clear what to keep doing and what to stop. Lesson times could fit around school, university or work. It was an intense period, but it was worth it.

    Xiaoyu Xie

  • SSAT

    I wasn't starting from zero, but the same mistakes kept showing up in my mocks. We could make the workload lighter during busy weeks at school or university. Lesson times could fit around school, university or work. A lot of my mistakes came from rushing through the wording of the question. I went into the exam much calmer than I would have before. I'm genuinely thankful to my tutor for being patient.

    Indah Permana

  • SSAT

    I wasn't starting from zero, but the same mistakes kept showing up in my mocks. I finally understood what was going wrong in Reading. We could make the workload lighter during busy weeks at school or university. My written answers became shorter, clearer and easier to follow. I went into the exam much calmer than I would have before. Thanks to TestPrep for helping me stay on track.

    Brianna Merritt

  • SSAT

    I was doing questions for Middle Level on my own but never had a steady routine. The feedback I received on Middle Level was clear and practical. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. I can now decide much faster when to move on from a question. I went into the exam much calmer than I would have before. Thanks to TestPrep for helping me stay on track.

    Tegan Whelan

  • SSAT

    The SSAT format felt unnecessarily confusing at first. One bad mock no longer made me want to drop the whole plan. Having the lesson move at my pace made the process feel much easier. Seeing several versions of the same topic made unfamiliar questions less stressful. My mock results gradually became more consistent. Thank you to my tutor and the TestPrep team.

    Denise Cruz

  • SSAT

    After my first attempt, I wanted the second round of preparation to feel more organized. Over time, Reading became one of the most organized parts of my SSAT preparation. One bad mock no longer made me want to drop the whole plan. My written answers became shorter, clearer and easier to follow. My confidence improved along with the results. Thanks to everyone who supported me.

    Sebastian Canales

  • SSAT

    At the beginning, we knew very little about the SSAT system as parents. Communication with the team was straightforward and our questions were answered. The class size kept our child from disappearing into the background. The lessons started being followed without constant reminders from us. Mistakes became something to work on rather than something to feel bad about. Thank you sincerely to everyone involved.

    Jihoon Cha

  • SSAT

    Having the lesson move at my pace made the process feel much easier. I finally understood what was going wrong in Upper Level. There was no overnight miracle, but the progress was easy to see. Thank you to my tutor and the TestPrep team.

    Riley Porter

  • SSAT

    A good connection with the tutor developed quite quickly. We were pleased with the support we received.

    Taeho Min

  • SSAT

    I finally understood what was going wrong in Elementary Level. My tutor made it easy to ask questions from the first lesson. I can now decide much faster when to move on from a question. Knowing what to study reduced a lot of the stress. My mock results gradually became more consistent. I'm glad I worked with my tutor through this process.

    Reagan Chapman

  • SSAT

    Our child had a clear goal but no steady study routine. Flexible scheduling helped during a demanding school year. Being able to fit lessons around school made the process easier. Joining lessons willingly was one of the clearest signs for us. A good connection with the tutor developed quite quickly. Seeing the change in our child made us very happy.

    Saki Inoue

  • SSAT

    The feedback I received on Middle Level was clear and practical. I never felt awkward asking the same thing again. I worked on keeping a steady pace instead of rushing the easy questions. I found a better balance between regular school and exam preparation. I wasn't trying to learn new topics at the very last minute. Thank you to my tutor and the TestPrep team.

    Jade Gilmour

  • SSAT

    The SSAT format felt unnecessarily confusing at first. The feedback I received on Upper Level was clear and practical. Near the exam, it was clear what to keep doing and what to stop. Practicing in the real exam format made test day feel much less unfamiliar. Knowing what to study reduced a lot of the stress. I'm glad I worked with my tutor through this process.

    Chaewon Nam

  • SSAT

    After each test, we looked beyond the score and reviewed the type of each mistake. I finally understood what was going wrong in Reading. After a while, the questions started to feel much more familiar. I'm genuinely thankful to my tutor for being patient.

    Sydney Harrington

  • SSAT

    I was taking Upper Level at school, but getting used to the exam questions took time. The mocks showed where my time was actually being lost. After a while, the questions started to feel much more familiar. Thank you to the tutor who stayed supportive until the end.

    Haeun Heo

  • SSAT

    As the exam got closer, I wasn't sure what I should actually review. After a while, the questions started to feel much more familiar.
