Are multiracial applicants favored in the admissions process? Is there preference towards certain races in multiracial applicants?
All of these questions are school dependent. Many schools do not consider race/ethnicity at all in admissions.
What’s the policy for schools that do consider race/ethnicity?
For schools that give a boost for race, it never hurts to be a fractional under-represented race.
It depends on the school.
There’s a Race in College Admissions FAQ at the top of this forum. Try posting there.
