Class policy:

The final course grade will be determined based on partial scores according to the following percentages:
Homework/Projects: 20%
Test 1: 20%
Test 2: 20%
Test 3: 20%
Final exam: 20%
According to the Catalog, the following grading symbols are used by SIUE: A-Excellent, B-Good, C-Satisfactory, D-Poor, and F-Failure (see Academic Policies and Requirements). The letter grades will strictly comply with these definitions. The thresholds for the letter grades are: A > 87%, B > 75%, C > 62%, D > 50%, and F ≤ 50%.
Grades will be based on written evidence in the submitted work. Answers without sufficient supporting work will be awarded zero score. Measurement units are considered an important part of the answer. Graduate students enrolled in this course will have more involved project requirements. In addition, different or additional exam problems will be considered for graduate students, as necessary.
