This course is the first one, where I finished and don´t have the feeling of knowing more. No, I´m totally confused and afraid of going forward with the next course.
Personally I think the texturing course is better. After reading your review, I think you're right about the confidence thing and that's probably why the texturing one is better to me.
There's always the ones before the CORE that you can watch as well. The exact same topics are covered:
