For one of my physics classes, it was like 10% HW, 10% class participation quizzes, 30% lab, 50% exams. The HW was optional (and your exam scores would replace your HW scores if you so chose) but the HW pretty closely followed the exam. The class participation quiz points were fully awarded as long as you showed up every day to lecture. The labs weren't skippable or cheatable because everyone had different measurements and you had to document every step of the way. The exams were personalized 1-10 such that you'd never be sitting next to anyone who had your same exam (and the questions were never recycled). Two pages of notes allowed on every exam. Apart from some high-tech cheating, I'd say it was a reasonably cheat-proof class. I don't know how applicable that model is to calculus though.
