Our daughter needed regular support with Chemistry. The small group offered peer learning without making it hard to ask questions. The lessons started being followed without constant reminders from us. It was good to see confidence returning over time. We thank the tutor and the TestPrep team.
Nina Martens
Over time, Physics became one of the most organized parts of my IMAT preparation. After a while, the questions started to feel much more familiar.
Rodrigo Braga
When I started preparing for IMAT, I wasn't sure what order to study things in. Lesson times could fit around school, university or work. Once I understood the reasons behind the facts, the questions felt less random. We could make the workload lighter during busy weeks at school or university. We didn't spend extra time on things I already knew. It was an intense period, but it was worth it.
Felipe Aguirre
Having the lesson move at my pace made the process feel much easier. Breaking General Knowledge into smaller pieces worked much better for me. I started noticing the reason for a mistake much faster. Thank you to my tutor and the TestPrep team.

Matias Figueroa
What annoyed me most was losing easy points because I rushed. 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. Going back to the lesson recordings helped when I forgot a small step. We didn't spend extra time on things I already knew. I'm glad I worked with my tutor through this process.
Abbey Elliott
The IMAT format felt unnecessarily confusing at first. I became much more comfortable asking questions in class.
