Math 2D

Hi I am taking Math 2D this coming fall quarter with Staff. I was wondering about the difficulty of the class and how often the textbook was used. From what I have read, it is better to buy the current edition of the math textbook due to homework problem issuses. I was wondering if that is the case with this class or if I can get away with buying an earlier edition.

If you guys have any other advice or tips, please post!

thank you!
