I recently noticed that a few of the courses I am required to take for my undergraduate program are also offered by an online university, and that they allow you to audit said courses relatively cheaply. Would it be a good idea to study ahead using these courses, or is such a thing considered unethical as it would give me an advantage when I take the course at my own institution? Am I generally required to report the audited courses when I later apply for graduate school (which would presumably look 'bad')?
Specifically I am in Canada if the rules vary by region.
