<p>I got a 5 in AP Calculus AB in 2008, but I'm having a hard time memorizing series and sequences and everything. It seems so much more complicating than last year, even though there's only little to learn.
Any advices on how to get through these??</p>
<p>Which textbook do you have? Look into your textbook, they would have a table somewhere which should summarize all the general formulas and the idea of the series, i.e geometric, alternating, direct comparison test etc. It's pretty easy once you know how to recognize them, then just practice with lots of problems. I am confident you would get it!!! Calc BC is fun...</p>
