I am not quite sure how long I have been studying, but I also work about 30 hours a week. I've finished chad's GC, OC, and QR.
About to get started on my Destroyer, but seems a little hard.
What I struggle with GC is that when I encounter a problem, I have no idea what the question is really about.
I know how to solve them, it's just that I struggle with finding out what type of problem it is.
