Overview
Class starts at 8:00 or 8:30 in the morning from Monday to Friday. Typically, mornings will start with a student synthesis of data, findings, and questions from previous day’s lab, followed by next lectures. Afternoon labs will most often be related to the morning lectures. The schedule is flexible and will be updated throughout the course.
