2 Unit examination results will be reported as the grade assigned by the faculty calculated to the first decimal place. These grades will be weighed according to course grading policy. In calculating the course grade, 0.5 will round up to the next numerical grade and 0.4 will round down to the next lower numerical grade. 1. The total laboratory grade will be based on an average of fourteen (14) laboratory experiments and an average of six (6) laboratory quizzes given through the semester. The experiment average will make up 80% of the final grade and the quiz average will make up 20% of the final grade. 2. Any missed lab will be averaged in as a zero (0). Students will have the opportunity to make up one (1) missed laboratory experiment during the semester with a valid excuse. There will be time scheduled by the learning assistant in charge of the lab for this purpose. 3. Any missed laboratory quiz will not be made up.
