The Checkin system allows you to submit programs, run preliminary tests, and view grading results.
In order to log into CS 270 Checkin, you need to be enrolled as a student in the CS 270 Checkin roster. If you are able to log in on the Linux department machines, and not on Checkin, then ask a TA to add your eID to the roster.
Please use your CS Department credentials. If you are an undergraduate student, then your username is your CSU eID (also used to access Canvas and RamWeb), but your password is specific to your CS account.
