Departmental advising
Advising for students who have declared a major.
Every LAS department has at least one academic advisor to assist its students. Plan on visiting your advisor before you register for classes each semester.
See your major/departmental advisor for:
- New student registration
- Major plan of study
- Department advising holds
- Semester schedule plans
- Degree completion plans
- Inquiries about course restrictions
- Registration errors
- To obtain approval for adding a second major or minor
- Study abroad exploration, course planning and approvals
- Research/internship opportunities/getting involved
- Information regarding campus resources
- Degree audit questions
Your advisor will also assist you in obtaining letters of recommendation, provide information about graduate and professional schools, and offer advice about vocations related to your major or curriculum. If it's required, you should have your major plan-of-study form completed and submitted to LAS Student Academic Affairs before the end of your fifth semester (60-75 hours). Ask your advisor for more information about this form.
Note: Unless otherwise indicated, non-majors or prospective majors are welcome to make an appointment with the departmental advisors.
