It’s good to plan (EC’s will factor in, for instance), but it’s also very dangerous to fixate on one school when it depends on earning one of very very few full ride scholarships.
You should absolutely strive for that, but start looking for honors colleges and scholarships. Be aware that deadlines will be Dec1st or even earlier at some schools.
And do ask your parents, don’t assume: what will happen if you don’t get a full tuition scholarship? if you don’t get a full ride? If the only full tuition scholarship you get is at Howard, or at another far-away college? Or at a college they haven’t heard of?
(I highly doubt they’d apply for Parent PLUS loans if they have the money to pay, for instance. But would they be eligible for Parent PLUS? Are they willing to take that on for 4 years? Just ask and make sure.)
