<p>Anyone got a book I could use to supplement this course.</p>
<p>I just moved to NY and kids here are way ahead of kids in Pennsylvania. Back in PA we didn't do trig identities or factoring cubed functions in precalc. Consequently I just failed my limits test here lol, and I've never gotten anything below a 100 in math before. Plus the teacher here just gives hella hard tests, I studied for 5 hours each night of the week, learned trig identities to the best of my ability. Indeed, i was feeling good when I took the review test in the back of my book on limits and got a 100. However, her questions were just redic. So, again, are there any books I could use?</p>
