MAT 261:  Differential Equations

Course Syllabus

FINAL COURSE GRADE (Updated on 05/07/07.)

*** This grade includes the take-home test, final exam, and received extra credit.***
The class average on the exam was 74%.  All final exams are propery of the Math Department and cannot be returned.  However, you are invited to make an appointment to stop by and survey your graded work. 
I wish you all a great summer and the best with regards to success in your future endeavors.
