Other graphing calculators are acceptable. I expect you to attend every class and remain for the entire class. I consider six hours missed as excessive , and you may be dropped from the class. Three tardies counts as one absence. Mathematical content is progressive.
New concepts depend on concepts learned in previous lessons.
Mathematics requires a disciplined thinking process. In class activities are an important part of class. NO make-up for group activities. If you miss class, you loose the opportunity to earn points toward your grade. You CAN NOT make-up missed quizzes and NO late homework papers accepted.
