Home assignments: Will be given every Thursday, you would have to submit your work next week Thursday into the slots behind the lecture room and you have to pick up the marked assignment one week later. Thus, every assignment has a cycle of 2 weeks. The text of the assignments will be posted on the class WEB site, followed by solutions one week later.

2020-05-01

There will be 11 assignments; the last assignment will not be marked and the solutions will not be provided but one of the problems will be included into the final exam.

Marking Scheme : For every question asked you will be given 2 points (OK), 0 1 point (minor errors) or (wrong solution). Total number of points earned will be posted on the class WEB site and updated once a

Please prepare your home assignment on any clean sheets of paper, show your complete work and make a frame for your final answer on every question asked, like this

2020-05-01

Student current standing will be updated once a week , for each section separately.

Please, watch your marks.

In a case of technical error by a marker or wrong mark given, see Sasha K., Room 258 (Physics) with your paper. He will be entering the corrected marks, and the corrections will be posted one week later . Please, do this within one week, once next assignment is in, corrections to the previous one will not be

There is going to be 2 midterm tests set for Monday, February 7 7:00-8:00 March 14 , p.m.

and 7:00-8:30 p.m.

Monday, Whoever (we expect very few) has conflict with this time (e.g., other classes) will be offered an earlier period, 5:15-6:45 p.m. No exceptions.

The mark distribution is as follows: Assignments 10 % Laboratory 10 % Mid-term exams (15+15=30 %) Final exam 50 %

If you have 2 nd Edition, should be OK in terms of the material covered, but … 1) The test problems аrе slightly different, though not always 2)The pages for the problems are different So, you would have to take
