How much did I mess up my chances of getting into college? [college calculus 1 B grade, IB math AA HL A grade; MD resident, 3.967 GPA, top 10% rank, 1530 SAT, <$50k, civil engineering]

I’ll probably have to take Calc 1 again anyways in college, because I’ve heard it’s pretty hard to get credit through IB (especially for more selective schools). My parents can contribute a total of $200k, the rest would have to be loans. I do want to do a 5 year masters program. I had GW on there because some of my friends received a lot of aid from there, but I’m still debating it.
