Graduate students look at majors.
Generally speaking, it is better in the average range.
Undergraduate course:
Not the best. But if you study hard, you can go to a good graduate school.

Double admission does not understand, early+routine? Maybe it suits you?
However, there are many universities in the United States, and there is little difference between TOP 100 (college+university) undergraduate courses.
