The ApplyingToCollege subforum on reddit is the most active forum for college applicants that I've seen in years. I try to stop by every day or so to check for questions related to UVA so I can provide some good information. When I see a certain issue come up multiple times, I know that I need to address it across my social media channels.
One of the things I see mentioned over and over again is a choice of major mentioned with questions about UVA admission. Right now, I'm seeing lots of students saying they applied to specific majors in the College of Arts and Sciences or School of Engineering.
At UVA, the only first-year applicants that are applying directly to a major are the students interested in Kinesiology. Otherwise, students apply to a school or college within UVA and have 1-2 years to declare a major. If this is a surprise to you, please be sure to read the applications instructions since you may have missed important information about applying to UVA.
Many students in those schools don't wind up declaring the major they thought they would anyway. There's no need to rush to declare. UVA students use the first few semesters to take a variety courses which will help them explore their options. After all, the subjects you have access to in college are a bit more numerous than the ones you had in high school.
