Withdrawal from a lecture course with a required lab constitutes withdrawal from both lecture and the lab components simultaneously. Show respect for your fellow classmates and your instructor. Your attitude is an important measure of your success in this course. If it is negative you will perform in a manner less than what you are capable of. Attend all classes.
Low grades are directly related to poor attendance.
If you must miss a class it is your responsibility to find out what you have missed and get the notes and assignment from other students. Excessive talking, disruptions and late arrivals will not be tolerated and you may be asked to move or to leave the classroom. Do not let yourself panic or become unduly frustrated. Remember, many others successfully learned these math skills. If you are in need of help, there are many resources available including tutoring and the academic support center.
