second offense will not be tolerated.
Tardiness
Arriving late is considered a classroom disturbance.
Excessive tardiness will not be tolerated.
Exams
On exam day you will need a pencil (scantrons),
calculator (batteries), and a student ID. If you are
late, you cant take the exam.

Fill in details while the topic is fresh.
Work problems.
Work more problems. Thenwork more problems.
Form your own study groups.
Exam review sessions.
Free tutoring may be available.
Make a commitment.Spend 2 hours per credit hour.
Ask questions.
If you have a question, so do others.
Ask in class, during office hours or in lab.
