Since it was mentioned upthread:
I got an email from my Algebra teacher. He was sending out the syllabus early (but he forgot to attach the document :p) and he also wanted to let us know we could start the class before the start of school if we want. Awesome.
But, he also said we don’t need the book. We just need the code for MyMathLab. I already bought the damn book. After debating, I decided to just keep it. It has the code I need and knowing myself the way I do, I’ll probably want the book at some point and regret returning it.
I just hope my stats teacher doesn’t send the same email.
