Getting a CS account

CS accounts are available to all students who are taking CS classes through the College of Arts & Sciences, and students majoring or minoring in computer science. In order to get a CS account you will need to go to the CS lab at 730 Commonwealth Avenue, room 302.

The first step in creating a CS account is to run the CS WebNew application on one of the Linux systems in the lab. The Terminal Assistants on duty will provide instructions for doing this. Once this is done, it may take up to five minutes for your account to become active.

Instructions are available at the Terminal Assistant (TA) desk in the front of the lab. Please see the TAs if you have any problems creating or using your new CS account.
