All solutions, lectures, and 486 materials are located in the secure folder.If you are a registered member of the course, you can access this area using your usual credentials: netid and AD password. If that fails, try adding "uofi\" (without the quotes) in front of your netid and try again. If that also fails, it's possible your browser is the problem. I cannot get in with Safari version 11.1.2 on my old Mac, but I can get in with Firefox and Chrome on the same machine, and a newer version of Safari on my iPad. FYI, the private folder is a utility area for course staff (instructor & TAs).
