# Syllabus

In the syllabus below, section and exercise numbers refer to the official course text A First Course in Linear Algebra. Section numbers and recommended exercises for the optional text by Lay (see the course info page) can be downloaded here.

Partial lecture slides (for following along in class) will be posted before each lecture. Full lecture slides and streaming video of the lecture will be posted after each class (click on the links in the syllabus below).

Questions on the midterm and final exams will be similar to the recommended exercises. Thus, students are strongly encouraged to work through enough of the recommended exercises until they have thoroughly mastered the material. Since it is very important to keep up with the pace of the course, students should work on the exercises associated to a given lecture before the next lecture. Keep in mind that there are many resources available to help you if you are having difficulties (see the resources page). Complete solutions to most of the exercises are contained in the text itself.
