17  May 59  final exams      semester ends 
Course grades will be determined from student performance on exams and quizes. There will be four exams: three 50 minute inclass exams and a final exam. The three inclass exams, which are indicated on the syllabus above, will be given during the hour normally used for lecture. These exams will be written by the instructors, and will test only the material covered since the previous exam. In contrast the final exam, which will be given during the week of final exams, will be a departmental cummulative exam. All of the exams will consist of problems similar to the homework problems assigned throughout the semester.
Homework will be assigned on a daily basis. The daily homework assignments will not be collected nor graded. However, it is important for learning and understanding that these problems be done as they are assigned. They should be thought of as required for success in the course (see Strategies for Success ).
The exams will be weighted as follows:
Exam 1  100 points 
Exam 2  100 points 
Exam 3  100 points 
Final Exam  150 points 
  
Total  450 points 
All quizzes will be announced ahead of time and usually weighted as 25 points, although the weighting may vary. The final course grades will be determined by the percent of points earned out of the total number of points (i.e. exams + quizzes). A straight scale will be used so that A's, B's and C's correspond to the percent ranges 10090, 9080 and 8070 respectively. At the discretion of the instructor these percentage cutoffs may be lowered to allow for "curving" of the overall difficulty of the exams. However they will not be raised for any reason, and in this sense are guaranteed grade ranges. Plus/minus grading will be used.
Math 267 is an introductory course on differential equations which presents solution methods. Like the calculus courses it is a problem solving course. Most if not all of the homework exercises are computational problems. The same can be said about the exam questions, which will be based on the suggested homework problems. Like any other skill, problem solving requires practice. And like any other skill, the more you practice the more proficient you become. In order to be successful in this class there are two time commitments on your part that are essential: i) attend the lectures regularly and ii) stay current in completing the homework assignments . If you have trouble with the homework you should seek help immediately so that you do not fall behind. The course moves quickly and falling behind may very well spell disaster. There are several sources of help.
