No one learns mathematics without doing the work. The key to success in any mathematics course is to do at least the minimum assigned work, and to do it on schedule. I will do everything I can to help you, work with you, and make this a meaningful course. So please decide early in the semester whether you can give the course the time and energy that it needs. You are no longer in high school.
Material is harder.
Expectations are higher. Material will be covered 2 to 3 times faster than in high school. Class time is at a premium. Not everything can be taught in class. Not every kind of example can be worked in class.
