For further explanation or clarification, or for an exemption or other special arrangement, the person to contact first for academic matters is your departmental advisor or student services staff. If they can't resolve the matter themselves, they will usually know who can. As a rule, it is faster and more efficient to solve problems at the department level.
See Services Within Schools for a listing of contact points within each of Stanford's schools.
