Weekly Quiz and Solutions
These short quizzes are given approximately once for every three lecture sessions. You should work through the quiz problems in preparation for the exam problems.
Exam Problems and Solutions
These exam problems are intended for you to demonstrate your personal mastery of the material, and should be done alone, closed-book, with just a calculator, the two permitted reference tables (periodic table, physical constants), and one 8 1/2" x 11" aid sheet of your own creation.
After you’ve taken the exam, watch the help session videos below for insights into how to approach some of the exam problems.
Exam Help Session Videos
In these videos, 3.091 teaching assistants review some of the exam problems, demonstrating their approach to solutions, and noting some common mistakes made by students.
Supplemental Exam Problems and Solutions
These additional exam problems from prior years’ classes are offered for further study.
