The textbook

Algebra: Chapter 0 by Paolo Aluffi

Your grade

Your grade will be the weighted average of your weekly homework assignments (30%, lowest grade dropped), weekly quizes (10%, lowest dropped), a midterm exam (20%), and an in-class final (40%).

The exams

There will be two exams in this course. One in class midterm

Midterm Exam 1: 12-1:15 p.m. Monday, October 29

and a comprehensive final exam:

Final Exam: 10am-1pm Saturday, December 15.

No make-up exam will be offered in this course. If you have to miss the midterm exam for a documented, legitimate reason, then your exam grade will be calculated using your grade on the final alone.

Homework

Homework accounts for 30% of the grade for this course. Most weeks it will be assigned on Wednesday and will be due the following Wednesday. Homework is due at the beginning of class on its posted due date. Most weeks, assignments will be posted on Thursdays and will be due on the following Thursday.

You are encouraged to talk to your classmates about the material covered in class and collaborate on homework. However any assignment you pass in must be primarily your own work. To avoid the pitfalls of plagiarism, please write up your assignments alone and independently. If you've worked on a problem with another student, please acknowledge that collaboration in your write up (of that problem).
