I know several people on here have used Chegg. Did you have the books mailed to your house or your residence hall/mailroom? If the latter, did the ups have any problems finding the right location?
One of my kids used Chegg. At most colleges you are assigned a mailbox number where you get your mail. If there is a package, you get a slip in your mailbox (and if your college is modern, maybe an email saying you have a package). Then you go pick it up in the office near the mailboxes. My kid’s colleges assigned the mailboxes at least a few weeks before school started (for one kid we shipped some bedding and stuff to her name and the box number, since we were flying across the country to her school).
