<p>I recently bought Barron's Math 2 prep book in order to "brush" up on my precal and whatnot for the the November 5 date. The problem is, I haven't done precal in a long time, and I forget a lot of my stuff. For example, polar and parametric equations, all those funky rules for reading roots and stuff off polynomial equations, etc...but I'm very good at algebra, functions and trig.</p>
<p>I've also looked at the sample questions in books like Sparknotes SAT Math 2 prep as well as the questions on CB's website, and for the main part, I am MUCH better at them then the questions in Barron's. So, just how much harder is Barron's than the real thing? If I can handle Sparknotes/CB questions, should I expect anything on the difficulty level of Barron's questions?</p>
