Academic Honesty
Both the Math department and UCI take a dim view of dishonest behavior with regards to assessments: submitting another's work as your own, copying during exams, bringing notes to exams, etc. Harsh penalties are in place for students who are caught; depending on the seriousness you may be given an F for the assessment, for the class as a whole, or even suspended from the University.
Other resources
While office hours and discussion sessions will hopefully be enough to get you through the course, other resources are available. In particular,
