I was doing questions for Upper Level on my own but never had a steady routine. I became much more comfortable asking questions in class.
Erdem Duman
Mistakes became something to work on rather than something to feel bad about. We were able to follow the mock results regularly. We were happy with both the teaching and the communication.
Johanna Meier
Breaking Elementary Level into smaller pieces worked much better for me. I stopped doing a huge amount one week and nothing the next. Timed work showed exactly which section was slowing me down. I left the exam feeling that I had done what I could. Knowing what to study reduced a lot of the stress. Thank you to the tutor who stayed supportive until the end.
Cristian Escobar
A quick check after each answer helped me catch small mistakes. Thanks to TestPrep for helping me stay on track.
Holly Stanton
Anxiety became more visible as the exam got closer. A good connection with the tutor developed quite quickly. Online lessons made it possible to continue without losing time on travel. The tutor's calm approach helped protect motivation during the intensive period. Joining lessons willingly was one of the clearest signs for us. The overall experience was positive from beginning to end.
Raul Tavares
After the first attempt, we looked for a calmer plan for the retake. The plan was adjusted when school exams became busy.
Toby Whitlam
Our son's school schedule was already very busy. Preparation looked calmer and more organized closer to the exam. Online lessons made it possible to continue without losing time on travel. With no more than six students, the tutor had time for everyone. We were happy with both the teaching and the communication.
Joao Tavares
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. Having the lesson move at my pace made the process feel much easier. I worked on keeping a steady pace instead of rushing the easy questions. I became much more comfortable asking questions in class. I was really happy with the lessons.
Intan Nasution
As the exam got closer, I wasn't sure what I should actually review. My preparation became much more regular and easier to track.
Erin Langley
I was doing questions for Writing Sample on my own but never had a steady routine. Near the exam, it was clear what to keep doing and what to stop. Discussing why the other choices were wrong helped more than I expected. A big thank you to my tutor for all the support :)
Piper Reynolds
I finally understood what was going wrong in Writing Sample. I learned not to spend the same amount of time on every line of a long text. I found a better balance between regular school and exam preparation.
Georgia Garland
Over time, Middle Level became one of the most organized parts of my SSAT preparation. My confidence improved along with the results.
Logan Russell
We weren't sure whether online lessons would be effective. We were able to follow the mock results regularly.
Qianyu Du
I was taking Reading at school, but getting used to the exam questions took time. Thank you to my tutor and the TestPrep team.
Brodie Redfern
After my first attempt, I wanted the second round of preparation to feel more organized. Even in a group lesson, the tutor knew where each of us stood. Practicing in the real exam format made test day feel much less unfamiliar. One bad mock no longer made me want to drop the whole plan. Questions from other students often helped me as well. Thanks to everyone who supported me.
Kai Lin
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. Breaking Upper Level into smaller pieces worked much better for me. By the end of each lesson, I knew what I was supposed to do during the week. Timed work showed exactly which section was slowing me down. I left the exam feeling that I had done what I could. The preparation felt calmer than I expected.
Bastien Gauthier
After the first attempt, we looked for a calmer plan for the retake. Mistakes became something to work on rather than something to feel bad about. The question bank made independent work between lessons much clearer. Communication with the team was straightforward and our questions were answered. Thank you sincerely to everyone involved.
Joel Ingram
I can now decide much faster when to move on from a question. I'm glad I worked with my tutor through this process.
Alana Clarke
As the exam got closer, I wasn't sure what I should actually review. Lesson times could fit around school, university or work. A quick check after each answer helped me catch small mistakes. I started tracking the type of mistake, not just the number of questions I completed. My tutor could see my reasoning and usually found the source of an error quickly. Thank you to my tutor and the TestPrep team.
Hamish McIntyre
I learned not to spend the same amount of time on every line of a long text. It was an intense period, but it was worth it.
Marco Gatti
Over time, Middle Level became one of the most organized parts of my SSAT preparation. I can now decide much faster when to move on from a question. My mock results gradually became more consistent.
Kaan Ekinci
When I started preparing for SSAT, I wasn't sure what order to study things in. Thank you to my tutor and the TestPrep team.
Chiara Gatti
Our child wasn't sure how to organize the preparation for SSAT. Thank you sincerely to everyone involved.
Thanawat Wongchai
As the exam got closer, I wasn't sure what I should actually review. After each test, we looked beyond the score and reviewed the type of each mistake. Learning when to leave a hard question made a real difference to my timing. Near the exam, it was clear what to keep doing and what to stop. Experiencing the exam format beforehand made test day much less stressful. I was really happy with the lessons.
