I bought the GT3 course. Marion is so good at breaking everything down, so they are easy to understand. Now I have to put those concepts into practice. Excellent way to learn!

I have recently finished the GT3 course and it’s very eye opening, and probably not only for this specific car category, but for sim racing overall.
The theory is very well presented and more importantly, easily translated to the track, with practical tips and exercises to put into practice aiming to directly improve/fix your driving.
I definitely recommend it. 10/10
