If you are already a BC student and plan to take courses anywhere outside of the regular day school of BC's College of Arts and Sciences (perhaps in the Lynch School of Education, in the Evening College, during the summer session, or at an entirely different institution), you must have your course credits approved by the Psychology Department as counting towards your Psychology Major.
For approval of courses taken elsewhere, you should provide the main office with information about each course, including the course syllabus. You should also provide the main office with a current copy of your Boston College DeGRE audit or your social security number. The main office will decide if a meeting is necessary after reviewing the relevant material. If you are asked to meet with the Director of Undergraduate Studies, you can set up an appointment by calling the main office (617-552-4100).
If you anticipate taking courses somewhere other than the regular day school of the College of Arts and Sciences, then you should make every effort to obtain prior approval from the Psychology Department. Doing so will help insure you receive credit for the course(s) and, thus, will help avoid having your schedule disrupted at some later time.
