===In Class Submission (Murray SaulAndrew's Classes only)sections==='''Arrange evidence (command output) for each of these items on your screen, then ask your instructor to review them and sign off on the lab's completion:'''
You may choose to:
* Submit screenshots of your work on Blackboard, in which case you don't need to come to the lab.
* Or come to the lab, show me your work, and talk to me about it. I want to hear what you've learned and answer any questions you have.
You'll get the same grade regardless of how you choose to submit your work.
