REQUIREMENT:

• Students should attend the discussion section every week.
• Homeworks are due 5:00pm sharp. No late homework will be accepted.
• There will be one midterm during the regular lecture hour, and a final exam at the end of the semester which will cover the materials of the entire course. The exams are close-book and close-note but you are allowed to bring two sheets formula.
• The course grade will be a weighted combination of homework (40%), midterm (20%), and final exam (40%).

ANNOUNCEMENT:

• The midterm will take place on 3/15 during the lecture hour. It is a close-book close-note exam, but you are allowed to bring two sheets of formula.
• HW-5 will be due 3/18 (Monday) at 5:00pm instead of 3/15.
• Midterm result.
• The final exam will take place on MAY 15, 3-6pm at 70 EVANS. It is a close-book close-note exam, but you are allowed to bring two sheets of formula.
