Attendance
Students are expected to attend class. If important circumstances prevent this, it is the student's responsibility to find out what was covered in class, what was assigned for reading or homework, and what special announcements (if any) were made. "Excessive absence" in this class will be construed to be absence from more than 10 percent of the scheduled class sessions, whether excused or unexcused, and will be subject to Administrative Drop as per University policies.

Tutoring
The Mathematics Department offers free tutoring for its introductory Mathematics classes, which includes MATH 263. The tutoring is provided in the Mathematics Teaching Laboratory (MTL) room 121, and will run through the Spring semester. See the schedule at http://math.arizona.edu/academics/tutoring/math300/.
Notice on the tutoring schedule that Statistics tutors (for MATH 263) are distinguished from all others: they are indicated by an asterisk (*). Do not attempt to ask Statistics questions of non-statistics tutors; they will not be able to help you. Plan your visits to coincide with the statistics tutors marked with a *.
