Okay, long story short, I signed up for this online program, that shows you a lot of rules, gives you practice, tons of examples, and then audio and video questions as well. It's pretty helpful... this is for Spanish... it has a course for a1 level, a2, b1, b2, c1, and c2...

I took the formal exam and scored as a B1 level... should I just test out of A2 and skip over to the B1 class and do the whole thing, or should I just do the a2 course in its entirety?

I'm asking cause I'm becoming impatient.

Do it in its entirety... there will be things in the earlier one you don't know even if you do test ahead. Like most things... how well you do depends on how well a base you have to build off on.
