I’m getting review books together for next year and I’ve heard that Peterson is, by far, the best AP Calc BC review book. I really need a good review book because our math program here isn’t too strong (we didnt learn logarithms until this year in pre-cal, don’t learn polor/parametric until Calc, etc.). However, everywhere I’ve looked online has been ridiculously expensive (cheapest I’ve found is $34 used on Amazon). Does anybody know where I can buy this book for a relatively low price (btw, I am aware there is a pdf online, but I don’t want to spend the money printing it off unless I really have to)
