Recap and review 

Classes are on Monday, Wednesday, and Friday, 1:50  2:45pm, in 436 Bolz Hall.
602 MW (Math Tower): M 34, W 1011, or by appointment.
We will use Introduction to Linear Algebra, 5th ed., by Johnson, Riess, and Arnold (Chapters 1, 3, and 4), and Elementary Ordinary and Partial Differential Equations Part II (Chapters 7 and 10), by Boyce and DiPrima.
The dates for the midterms and final exams are as follows:
First Midterm:  Wednesday, September 27  1:50  2:45pm (in class)  436 Bolz 
Second Midterm:  Wednesday, November 1  1:50  2:45pm (in class)  436 Bolz 
Final Exam:  Wednesday, December 13  2:00  3:45pm  436 Bolz 
Be sure to note these dates carefully now and make plans accordingly.
Practice problems for Midterm 1 are here. Solutions are here.
Practice problems for Midterm 2 are here. Solutions are here.
First Midterm:  20% 
Second Midterm:  25% 
Final Exam:  30% 
Homework:  25% 
The homework component will be computed out of a total of 90%. This means that if there are a total of 100 points, and you score 72, your homework grade is 72/90 = 80%. (I'm doing this instead of dropping a lowest homework.)
