I've been reading up on the threads asking when to buy textbooks, and I'm conflicted!
Most people say to buy them after the first classes (in case books change), but most people also say you need to get used books before school starts because they go fast!\
I'm in Engineering I this September! What do I do? I plan on buying used, but it seems like the editions change from year to year for some courses...does this mean the textbook is different?
