Discussion Session
During Thursday lecture every 3rd week, starting in the 5th week of the semester. In the discussion session we will review basics, investigate material covered in class from a different perspective, answer questions, and discuss recent developments in the field.
Homework
Homework assignments are given every week, starting in the 2nd week of the semester. Each problem set is due one week after it has been handed out.
Homework Submission
Homeworks will be submitted electronically, as pdfs. Homeworks may be prepared by hand, in LaTeX, or even using Microsoft Word. If by hand the homework need to be scanned to pdf. Note that student will need to name file "Name_hwX.pdf" (e.g. second homework file "Arun_hw2.pdf") in order to submit it.
Grading
Homework: 0%, Quizzes: 0%, Mid Semester Exam: 40% (20% each), End Semester Exam: 40%, Laboratory: 20%
