I strongly encourage you to ask questions in class. Don't be concerned about interrupting the lecture. In addition to the main lectures, there will be 2 hours per week of recitation on Mondays and Wednesdays from 11 am till noon. Wednesday recitation will be a regular one. These problems have to be solved in groups from 2 to 4 people each.
All homework is due by last day of class.
The schedule contains a list of the problems and their due dates for the semester. The schedule is subject to change during the semester. Each problem set is due before lecture begins. Late sets will not be accepted without a compelling reason given to Ricardo. Your TA does not have the authority to accept late homework.
