So I went onto my portal and it says I need to get 2 required textbooks for my math 130 calculus 1 class. But the 2 books seem to be identical. Do I still need to purchase both of them?
This is a good professor question. Shoot him/her an email. Sounds like a mistake, perhaps you can get one or the other. Or maybe one is a complement to the other. But only that person knows for sure.
Is one the physical version and the other the electronic version? Or is one the companion study guide/extra problem sets?
What are the two books that appear the same?
generally, it’s a good idea to go to the first class before you buy the books. that way you can ask the prof how they will be used before parting with the cash.
