Midterm 1: March 13, in class.
Midterm 2: April 15, in class.
Final Exam: as scheduled on Spire.
Midterm 1, 20\%, Midterm 2, 20\%, Final, 30\%, Homework 30\%. (Standard scale for final grade: A: 90\%, B: 80\%, etc.)
If you have a legitimate (i.e., multiple exams at the same time, medical problems, emergency absences, religious observances) scheduling conflict with any of the exams, please notify me of the conflict as soon as you become aware of it. Please note that previously arranged travel plans are not a valid reason to be given a make-up exam.
Calculators are useful auxiliary tools for the course. However, it will be expected that you can work all of the problems without the aid of a calculator. Calculators will be permitted on the exams, but it will be expected that all non-arithmetic work is present and explained in your answer.
Homework is collected and graded on a (roughly) weekly basis. (Time of collection: TBA.) Each homework must be well organized and neatly written. Homework assignments will be posted at the bottom of this page (please check often). We plan to use Gradescope. Homework will be graded by a special grader.
