If BU senses your child is undecided she may be admitted to their College of General Studies program with a January start in London. Students who apply to BU may be accepted for CGS without choosing it. Just one thing to know.
I know you’re not a Northeastern U fan but for anyone reading the thread who might be interested, their Explore Program for undecided students is excellent and unlike some other schools you can choose engineering, business or CS later without having been admitted to those schools.
