The group never had more than six students, so it was easy to stay involved. I finally understood what was going wrong in Time Management. My preparation became much more regular and easier to track. A big thank you to my tutor for all the support :)
Felipe Montalvo
We weren't sure whether online lessons would be effective. We were able to follow the mock results regularly. The plan was adjusted when school exams became busy. The tutor's close attention to weaker areas gave us confidence. It was good to see confidence returning over time. We were pleased with the support we received.
Felix Schmitz
Over time, IQ & Logic became one of the most organized parts of my YÖS / TR-YÖS preparation. I became much more comfortable asking questions in class.
Madison Chandler
Our child wasn't sure how to organize the preparation for YÖS / TR-YÖS. Preparation looked calmer and more organized closer to the exam.
Shota Takeuchi
The YÖS / TR-YÖS format felt unnecessarily confusing at first. My confidence improved along with the results.
Hina Maeda
I was taking Mathematics at school, but getting used to the exam questions took time. I started noticing the reason for a mistake much faster.
Mika Valdez
Our child had a clear goal but no steady study routine. A good connection with the tutor developed quite quickly. Thank you sincerely to everyone involved.
Ilaria Bellini
I was close to my target, but my results changed a lot from one test to the next. Thank you to the tutor who stayed supportive until the end.
Finn Krause
Breaking Geometry into smaller pieces worked much better for me. Knowing what to study reduced a lot of the stress.
Claire Blanchard
Our son's school schedule was already very busy. Being able to fit lessons around school made the process easier. Flexible scheduling helped during a demanding school year. The plan was adjusted when school exams became busy. We would recommend the program to students and families in a similar situation.
Elise Renard
I finally understood what was going wrong in Mathematics. I became much more comfortable asking questions in class.
Linlin Li
Breaking Mathematics into smaller pieces worked much better for me. I went into the exam much calmer than I would have before.
Joao Branco
The feedback I received on IQ & Logic was clear and practical. I stopped doing a huge amount one week and nothing the next. A quick check after each answer helped me catch small mistakes. There was no overnight miracle, but the progress was easy to see. The preparation felt calmer than I expected.
Rafaela Oliveira
After the first attempt, we looked for a calmer plan for the retake. We thank the tutor and the TestPrep team.
Danica Kovac
A quick check after each answer helped me catch small mistakes. The preparation felt calmer than I expected.
Mette Lindberg
I was doing questions for Mathematics on my own but never had a steady routine. Even in a group lesson, the tutor knew where each of us stood. Learning when to leave a hard question made a real difference to my timing. My tutor usually asked me to explain my thinking before stepping in. Thank you to my tutor and the TestPrep team.
Johan Ilic
The feedback I received on Geometry was clear and practical. Seeing several versions of the same topic made unfamiliar questions less stressful. I started noticing the reason for a mistake much faster.
Yuki Sato
I was doing questions for IQ & Logic on my own but never had a steady routine. I went into the exam much calmer than I would have before.
Ignacio Paredes
I finally understood what was going wrong in Mathematics. I wasn't trying to learn new topics at the very last minute.
Valentin Berger
I was close to my target, but my results changed a lot from one test to the next. I started tracking the type of mistake, not just the number of questions I completed. Lesson times could fit around school, university or work. A quick check after each answer helped me catch small mistakes. My mock results gradually became more consistent. I was really happy with the lessons.
Sloane Whitman
Everyone recommended different resources and I kept switching between them. I went into the exam much calmer than I would have before.
Eunji Ahn
After my first attempt, I wanted the second round of preparation to feel more organized. I stopped doing a huge amount one week and nothing the next. I started seeing shorter solutions that were easier to check under time pressure. Thanks to TestPrep for helping me stay on track.
Onur Gurbuz
Seeing several versions of the same topic made unfamiliar questions less stressful. I'm glad I worked with my tutor through this process.
Loic Gauthier
We were realistic about what could be improved in the time available. Over time, IQ & Logic became one of the most organized parts of my YÖS / TR-YÖS preparation. I became much more comfortable asking questions in class. Thanks to everyone who supported me.
