Each student is required to post at least two questions during the unit period. The first post for a unit must be submitted at least 48 hours before the due date. Questions can be of Fuzzy or Challenge in nature.

• If you are fuzzy about a concept, please typeFuzzy at the beginning of your post and the instructor and/or classmates will respond.
• If you are confident about a topic and want to challenge your peers, typeChallenge at the beginning of your post.

Thank you!
