Adding Math Competitions Preparations on Khan Academy

I am currently studying for the AMC 8, a rigorous math competition. I would like it if there was a course for AMC 8 preparations, as well as for AMC 10 and AMC 12, and also AIME I and AIME II if possible. (I saw a video that solved an AIME problem, but I'd like more videos to prepare for future competitions.) I really appreciate it if courses for these competitions and others were added to Khan Academy.
