who are academic advisors in college? (at least a paragraph about them)

Generally they are faculty members in the advisee's department. Some colleges, however, have a separate general studies program in which all freshman and sophomores enroll. The general studies department has advisors; these advisors may or may not be on the faculty. Students' files are transferred from the general studies problem to the major field department upon completion of the sophomore year (or 60 hours) and another advisor then handles the advising responsibilities through graduation.

thank you.

Academic Advisors serve the student by explaining a program of study and by informing the student what courses need to be passed prior to graduation. The Advisor does not attempt to evaluate the student's strengths or weaknesses nor aid them in choosing a program of study or their major.
