However, planning for the transition from being a student to having a career requires knowing more than you can get from academic advising alone. If you want to know what a class is like, ask a student who has already taken it. Keep in mind that classes and rules change and that your situation may be different. Talking with friends and acquaintances is a good first step, but don't stop there. Professional advisors have experience helping students deal many of the same situations you will face.
Professors are advisors.
Professors you talk with after class or in other situations can also advise. Professors know subject matter and can help you ask yourself whether the math requirements or chemistry requirements are going to be as easy or hard as you think. Professors are the best source for finding out how a course will be taught next time it is taught. Students planning to get an advanced degree should make a special effort to talk with a professor as an advisor. The variety of advising opportunities means that there is no single place to get advising, you may go to many advisors as your questions change.
