This is the course-wide webpage with common guidelines for all learning sections. Please consult your section webpage (below) for additional information.Enrolling and Overrides
Students waiting to enroll in the course should attend class and regularly check SPIRE to see if a slot in the desired section opens. If an override is still needed, please wait till AFTER THE FIRST WEEK OF CLASSES to contact your (desired) section instructor, cc'ing the course chair Professor Rob Kusner firstname.lastname@example.org with the following information: (1) sections of the course which conflict with other courses on your academic schedule, and (2) your desired section of the course. (Unfortunately, in order to keep the sections balanced, we cannot guarantee that you will be assigned to your desired section.)Syllabus and Weekly Schedule

Textbook and On-line Homework
The course text is Linear Algebra and its Applications (5th edition) by David Lay, Steven Lay & Judi McDonald.
MyMathLab is required for this course. An electronic copy of the
textbook is included in your purchase of MyMathLab.
Go to www.mymathlab.com and use the Course ID for your learning section (provided by your section's instructor).
On-line homework and quizzes will be assigned through MyMathLab by your instructor. Here are suggestions from Pearson for getting started with MyMathLab.Exams
There will be two midterm exams and a final exam. Past exams are available here.
You are allowed one 8.5" x 11" sheet of notes (both sides, in your own handwriting). 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 your instructor (please cc the course chair Rob Kusner email@example.com) at least one week's written notice for a midterm exam and at least two weeks' written notice for the final exam. Your instructor and the course chair will evaluate your request and your instructor will arrange for the make-up. Other make-up exams (for example due to medical emergencies) will be handled directly by your section instructor. Make-up exams will not be given to accommodate travel plans.Midterm I

!!!!!!!!THERE WILL BE NO MAKE-UP/EXTRA-TIME SESSION!!!!!!!!
If you have a contract with DS, please contact them IMMEDIATELY to schedule your exam there.
They require a week advanced notice, so you must contact them BEFORE Monday 12/9/19
The topics for the final exam may include the following sections of the textbook: 4.5, 4.6, 5.1, 5.2, 5.3, 6.1, 6.2 (and possibly some of 6.3, 6.4, 6.5).
Please work through the problems at the end of Chapters 5 & 6 before the exam.
Please remember: you are allowed one 8.5" x 11" sheet of notes (both sides, in your own handwriting) for the final exam; calculators and the textbook are not allowed; and you should bring your student ID (UCard).Grading
The four course assessments are equally weighted (25% each): Midterm I; Midterm II; Final exam; Homework, quizzes and class participation (determined by your section instructor).Course grades correlate to overall course percentages roughly as follows:
UMass Amherst is committed to providing an equal educational opportunity for all students. A student with a documented physical, psychological, or learning disability on file with Disability Services may be eligible for academic accommodations to help them succeed in this course. If you have a documented disability that requires an accommodation, please notify your instructor during the first two weeks of the semester so that we can make appropriate arrangements. It is also your responsibility to notify Disability Services (normally at least one week in advance) if you wish to take an exam there.!!!DRAFT!!! (Still under reconstruction! ;-)
