This is going to be an issue with BU where the acceptance rate is very low.
Do you plan to take the SAT or ACT?
No you won’t be applying EA. unless something changed this year, BU doesn’t have early action. They only have binding early decision 1 and 2.
From the BU website:
Early Decision and Early Decision 2 are application options available at Boston University by which students apply and receive an admission decision early (see deadlines), and, if admitted, commit to attend BU by withdrawing applications to all other schools.
I will add, with your current grades, I would not suggest an early application anywhere. You want the schools to see your (hopefully) strong first semester senior year grades.
