__REQUIREMENT:__

- Students should attend one of
the discussion sections every week. Discussion starts from the 2
^{nd}week (8/31-9/4). - Homeworks
are due 5:00pm sharp.
.__No late homework will be accepted__ - Please send your homework to Daniel by email. Pdf format is preferred. If you cannot create pdf format, jpg and png files are also accepted (make sure to have a clear resolution).
- There will be one midterm during the regular lecture hour (tentative Oct. 16), and a final exam (Wed, Dec 16, 7:00-10:00pm) which will cover the materials of the entire course. Both the midterm and the final exam are open-book and open-note exams.
- The course grade will be a weighted combination of homework (40%), midterm (20%), and final exam (40%).
- If you have questions on your homework grade, you should talk to the TA or Professor within 2 weeks after the homework is returned. Grade won’t be changed after two weeks.

__ANNOUNCEMENT:__

- To make it
easy to track your homeworks, please use the
file name of “Lastname_Firstname_hw1”
when sending your HW#1 to Daniel by emails and follow this format for the
rest of homeworks.
- The midterm
will be on Friday Oct 16 during the lecture hour. It is an open-book and
open-note exam and will cover materials of Ch1-3. I will send you the exam
by email at 1:10pm (you are responsible to ensure that your email works).
You must return your midterm before 2:00pm by email to Daniel at
“daniel.gardeazabal@berkeley.edu”.
. Pdf file is preferred but jpg and png files are also accepted. Name your file with “Lastname_Firstname_midterm”. I will open my zoom during the exam in case you have questions.__No late midterm will be accepted__
