It is AB for those who asked.
I don't know MOST of my trig integration and differentiation formuals. I keep studying the list but I just don't use them enough to remember them all.
I've been doing OKAY on the sample tests, but not great, and that's why I'm worrying. Last one I took I got 30 right out of 45, 12 wrong, minus 1/4 each equals minus 3, so I got a 27 out of 45. Multiply that by 1.2 and my score out of 54 is 32. I think that's BARELY a 4 for that test, but that doesn't include the free response.
I'm really bad with problems that involve a special function such as h(x), particle problems, and a couple other types I can't think of right now.
