So, it seems that for some certain classes, including general chem and calculus, we need to buy access codes to do our homework online as well.
But since these things expire, it's impossible to buy a used one, and the new ones may not be available through cheaper online retailers (such as the calculus book)
the access codes can be purchased separately, but cost more money as well
therefore, the best option is simply to buy the books at retail price from the bookstore?
or are there other ways to save money on this
This is pretty bad, the chem and math books alone cost 400 dollars with tax...
