Not doing too well wtih the training

I feel like I need to start all over again, with this 9 hour class.

Was it the beginners series? Where did you get stuck? Often times I have to remind myself that in almost all sports, music even activities like driving - I required and dedicated myself to practice. For some reason the idea of practice doesn’t seem as prevalent in my Computer studies, but maybe it is ok. When we start, maybe we first learn to practice! Musicians practice many hours a week to get good. Shouldn’t I do the same?
