Course Policies and Information

• Grades in the class will be based on the following factors:
  • Final Exam %40
  • Midterm 1 %15
  • Midterm 2 %15
  • Midterm 3 %15
  • Homework %15
  The final exam will be a common exam for all sections of MA 266. This class will use +/- grading. There will also be a few "Challenge Problems" for extra credit throughout the semester.
  
• You will not be allowed to use calculators on any of the midterms or the final.
• Homework will generally be due on Fridays, however you should always check the due date on the homework page. I strongly prefer that you turn the homework in in class, but it is due into my mailbox in Math 419 (or to me in my office if I'm there) by 5:00 pm on the due date. No late homework will be accepted, however I will not count your lowest homework score towards your grade.
• The textbook for the course is the ninth edition of Boyce-DiPrima's Elementary Differential Equations and Boundary Value Problems. Earlier editions of the book contain essentially the same content, but you are warned that the homework exercise numbers may be different.
• The coordinates for the midterm exams are as follows.
  • Midterm 1: 9/27, 8:00 - 9:30 pm, WTHR 104.
  • Midterm 2: 10/28, 8:00 - 9:30 pm, ARMS 1010.
  • Midterm 3: 12/2, 8:00 - 9:30 pm, WTHR 104.
• You can find a practice final exam here. The final will take place Monday 12/13, 3:20 - 5:20pm in LAMB F101.
