Lab Mechanics

Lab is graded on attendance and participation i.e. showing up and filling out an online check-off form as you work, with credit being awarded for a sincere effort as opposed to getting every detail correct. If you have any questions, please feel free to ask me!

For getting help in CS107 generally, please see the course website on the office hours mosaic each week and the EdStem forum. My office hours are typically:

  • Tuesdays, 1:30 - 3:30 PM, CoDa Basement 🏙️

The hours may vary by week, so the calendar has the most up-to-date information :)
