RG,
We enthusiasticaaly welcome "non-traditional" applicants. Our students come from a variety of backgrounds, including education, public service, non-profits, engineering and science, as well as more traditional areas such as finance, marketing, and consulting.
1. If you have a weak GMAT score, you might consider retaking the exam, concentrating on the section you scored lower on. Preparedness for the coursework might also be shown through undergraduate courses such as statistics and calculus and/or through work.
2. Please see my above comment. Applicants from the non-profit world are not looked down upon in any way!
3. We do have joint degrees with several other Yale programs. Please see our website for more information:

4. SOM is committed to a diverse student body. Of the incoming class, 38% are women, 8% are historically under-represented minorities and about 21% are international. We have several student clubs that ensure a welcoming presence on campus, including Women in Management, The Black Business Alliance, The Hispanic Advisory Council, Q+ Gay/Straight Alliance, and several international clubs. Please see our website for a complete list:
