Grading Policy

•  Course components: Question of the Day 7%

Mid-Term Exam 1 20% Mid-Term Exam 2 20% Final Exam 20%

Laboratory 33%

•  Letter grade breakdown: A = 90%+; B = 80 – 89%; C = 70 – 79%; D = 60 – 69%; F = < 60

Question of the day

•  We will set up a schedule where one student will pose a question to the class about one of the main topics from the last lecture. Rest of the class will turn in their answer, after which the student asking the question will explain the answer

•  Correct answer = 1 point; Incorrect answer = 0 points

•  Questions will count 7% toward your total grade

•  EXTRA CREDIT: By answering all Qs correctly over the entire semester, you can earn up to 3% extra credit

6

Homework •  Regular homework will NOT be assigned, HOWEVER:

•  Reports on the labs will have to be turned in for a grade

•  NO late reports will be accepted…

•  Format: Type it or write neatly, and use proper grammar & punc.

•  Working together: Encouraged, however you must turn in your own assignment, using your own words. Any student who fails to follow this rule will receive zero credit for the question, and if the offense is severe, for the assignment.

•  Free lab pass: Your lowest lab score will be dropped assuming you turn them all in. If you miss a lab for any reason, that counts as a “0” and that will be the lab that is dropped.

Exams •  Two midterm exams •  Final

•  Make-up/early midterm: •  Will not be given except for an excused illness (doctor’s note required) or family emergency •  Anyone with conflicts due to extracurricular activities

must provide at least 2 weeks notice with appropriate signed paperwork

Make-up exam will be substantially more difficult than the exam given to the rest of the class.
