Understanding what you are responsible for as a student is the first step to avoiding academic misconduct. There are many resources on campus and online that can help you make sure you are acting with academic integrity.
Your best resource are your instructors. If you aren’t sure if what you’re doing is academic misconduct, ask your instructor. They will be able to tell you if things, like collaborating on an assignment or looking at an old test, are OK or not. Your instructor will appreciate that you asked instead of doing it and hoping it would work out.
