Calculus is a college level class, and as such, most of the emphasis will be placed on how well students do on assessments (tests and quizzes). As a result, student grades are calculated in the following manner: 10% for daily work, and 90% for assessments.
Daily work is collected at the end of every chapter on the day of the chapter test. The students are well aware of this fact, and will probably be scrambling the night before the test to finish any work that remains undone (unless they are not procrastinators, then it will already be done!).
At the bottom of the page you will find the PowerPoint lessons for this class, available usually after the day the material was presented in class, but occasionally the same day. This is the exact same presentation as was given in class, minus any bad jokes and commentary on my part.
