TuTh 2:30-3:45PM, Goessmann 152

University of Massachusetts Amherst

  • Final exam will be Monday, Dec 18th, 10:30am-12:30pm in Boyden Gym.

    You are allowed one 8.5" x 11" sheet of notes (both sides). Calculators and the textbook are not allowed on the exams. You should bring your student ID (UCard) to each exam.

    If you have a documented conflict for one of the exams, in order to take the make-up exam you must give the course chair Matthew Dobson at least one weeks' written notice for a midterm exam and at least two weeks' written notice for the final exam. Make-up exams will not be given to accommodate travel plans.

    Students who are eligible for extra time should contact the Disability Services in one week advance to arrange their accommodations.

    Matthew Dobson will post a practice final (and possibly its solutions later) on the main course page, linked above. Check that page for all the updates.
  • In-class review for the final exam on Tuesday, December 12.
  • Additional office hours between 1-3:30 on Thursday, December 14.
    (By general demand, I will hold the additional office hours in the afternoon instead.)

Contact and office hours

The best way to contact me is via e-mail -- my last name AT Please make sure to include "Math 235.3" in the subject line of each one of your class related e-mails, and do not rely on e-mail correspondence over night or on weekends.

Office hours: Tuesday and Thursday 1-2 pm, or by appointment 4-5pm at LGRT 1326.

Homework and class participation

25% of your grade (in addition to the %75 from the midterm exams and the final) will be based on homework, quizzes and class participation. Online homework will be assigned with a due date after the corresponding section of the text is covered in class. Please check your MyMathLab account regularly for due dates, which might be modified during the semester. Late homework (any part you complete after the due date) will be graded with 50% deduction -- no matter what the reasons are.

Important notes for Section 3

I would like to discourage you to use laptops, ipads, smart phones, cell phones, etc. during our class, which not only distract yourself, but also anyone sitting around you.

Make-up exams will not be given to accomodate travel plans.

No calculators are allowed during exams. You may use calculators to check your homework solutions, but credit will be given only for answers showing all your steps (unless mentioned otherwise in the assignment).

If you have a documented disability that requires an accommodation, please notify me within the first two weeks of the semester so that we may make appropriate arrangements.


You can find sample midterm and final exams given in earlier semesters (gathered by Eyal Markman) at this link. These might be useful for practice purposes; some even come with solutions. Keep in mind that the problem types (and even the subject focus for a midterm exam) vary each semester.

Videos of lectures and course material on Linear Algebra (including exams, assignments, and their solutions) can be found at MIT OpenCourseWare.
