Math 121A - Linear Algebra
Class is scheduled for MWF 2:00-2:50pm in
MSTB 124.
Office Hours: MF 11-11:50am,
Rowland Hall 410F.
Course Information
The syllabus for the course can be viewed here and contains a complete
list of the topics covered during the quarter and the approximate time when they will be covered.
No question is a stupid question! You are welcome to ask questions in class, in discussion,
and during office hours and you are required to ask one weekly question by email. The latter is
called YAQ (You Ask a Question). Please send your questions to the instructor using
YAQ as a subject line by 5pm of each Friday.

It is highly recommended that you try and solve as many homework
problems from the textbook as you need beyond the weekly assignment.

Grading and Exam Policy
Remember that you start earning your grade the first day of classes. The best
way to obtain a satisfactory grade is simply to work regularly on the material,
to be pro-active and engaged, and to ask questions as soon as they arise.
Your performance in the exams is more often than not a reflection of your work
habits rather than of any great last minute effort. Better study habits also have
the added benefit to increase the chances of the knowledge acquired in class becoming
permanent and thus of making your life simpler in any subsequent math course you would
encounter on your path.
The grade will be based on your performance in the final examination (40%), in the
midterm (30%), homework (20%) as well as YAQ (10% each). Quizzes are mandatory and
a prerequisite to obtain a passing grade but they will not factor into the
computation of the grade.
Examinations are scheduled for:
- Midterm: Mon, October 28 in class
- Final: Fri, December 13, 1:30-3:30pm
The final grades will NOT be curved.
Cheating will be accepted under no circumstances and whoever is caught cheating will
automatically receive an F in the course and her/his Dean will be notified. Only fully
documented absences from exams justified in advance will be accepted. Unjustified no shows
in an exam will be graded with an F.
A Few Tips
Solve Homework problems regularly.
Read the material covered in immediately preceding classes before coming to class.
Ask any questions you might have timely and do not wait until the last minute.
Direct your questions to the course instructor and/or TA. Discuss the material and the
homework problems with your peers.
Use homework assignments and quizzes to test your understanding of the material and your
ability to solve problems within a time constraint.
