A check-in is just a weekly opportunity to score some points and ensure that you are keeping up with the course content. The requirements vary from week to week, but may involve responding to a survey, taking a brief online quiz, or participating in a discussion forum. They are due by midnight on the designated day.
Please complete this quick survey to help me understand your background and interests.
Then log in to Piazza and post to the follow-up discussion for Check-in 1. In your post, introduce yourself to the class and tell us about your interests – in computing and elsewhere.
