<p>I don't, at all. I'm self-studying Cal BC from Princeton Review, and I have most of it down pat. (65-70% of points on practice tests). But I skip every series question because I just flat-out don't get it. With 7 days left, how can I get a crash course in this subject?</p>
<p>Look up “patrickjmt” on YouTube</p>
<p>I understand series quite well, but I am quite annoyed that I keep on forgetting the many tests and conditions. Well, look like I have to review again. (Good thing that the Larson textbook has a nice table of tests) And ratio test is indeed the best test, hoping that the limit does not equal to one.</p>
<p>Straight from the ARCO book, a mnemonic to to help you remember the tests:

<p>^that’s a nifty way to remember all the tests. But I too have trouble with remembering the conditions for diverging or converging or inconclusive results… sigh</p>
