The calc BC test is coming up, and I don't really know anything about series, (I was studying for the SAT while the teacher was on that unit, and I haven't made time to study it for it except for now). I'm good enough in the rest of the topics other than maybe polar but what do I need to know about convergence tests and just series in general? Any good video that teaches what I need to know about series without taking 6 hours? Thank you guys
