I emailed my professor about a week ago to ask about the booklist, because this class wasn't posted, and the professor has not responded yet. Should I be worried? I need to know my books...

Don't be worried!! First, I would definitely send a follow up message to the professor, asking if he or she received your previous email and restate your interest in knowing the book list for the fall term. I would also keep checking the Bookstore's website to see if it has been posted yet as well. A lot of professors are even good about giving a couple of days to students to pick up books once classes start. Good luck :)

Feel free to ask me anything about SMC :)
