Help Desk:
Starts January 17:
Mon, 3:30 to 6:00, Room 165 Phys
Tue, 2:30 to 6:00, Room 106 Biology
Wed, 3:30 to 6:00, Room 165 Phys
One of the class instructors (Eric,
Sasha, Ron) will participate in Tuesdays
sessions from 04:00 to 06:00 and will be
answering on any questions.

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.
21/07/2015
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), 1 point (minor errors) or
0 (wrong solution). Total number of
points earned will be posted on the
class WEB site and updated once a
week
21/07/2015
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
21/07/2015
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
21/07/2015
considered.
There is going to be 2 midterm
tests set for Monday, February 7
7:00-8:00 p.m. and Monday,
March 14, 7:00-8:30 p.m. 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.

Textbook to be used:
Boylestad's Circuit Analysis,
3rd Canadian Edition,
by R.L. Boylestad et al.
Available in the bookstore

If you have 2nd 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
care of 1) and 2)
