Can Khan Academy provide a Teacher overview that offers a completed Computer Programming Guide. So that we don't have to memorize every issue. CodeCombat does this and it is SUPER helpful. Basically, it shows the student work on one side and the correct code on the other side. It really helps us (teachers) to be able to give quick and efficient feedback for students. i.e. "Check your coding on like 7" rather than having to run from desk to desk, student to student like a mad man.
