4. BYU CS 124Lab 0 - Warm-up Lab4 Lab 0 – Warm-up Lab 3.Setup a CS user account. Warm-up Lab If you are using your own computer, you can still set up your account. If you are using a computer science department computer, then you should already have an account setup for you. (If you are setting up an account for the first time you may need to use your RouteY ID as your username and your student number as your password.) Note: you may be required to change your password at this time.
