<p>I did a few practice problems from my old test prep book, then I just jumped in and took it - I assumed that extensive studying would be a bad idea because you might place higher than you should. I guess just try to represent your abilities the best you can, which for me wasn’t by cramming. It was helpful to do a couple problems just to remember the notations (personally, I haven’t taken calculus in a couple years, but you probably don’t have that problem…)</p>
