The "conditions" to get in?

I know US schools give mostly unconditional offers, but like UC schools, does BU have a “condition” to get in? (Like do not get below a C on senior grades)

I cant find any links to it, and on the admissions page it only says something like “keep your academics as it is now” so im not sure.

Also, does anyone know what happens if theres a huge drop on IB scores?

Most US schools, including BU, just don’t want to see a huge drop in your grades after they accept you, so no D or F. As for IB, US schools don’t really care about your predicted scores vs what you actually get since they don’t accept you based on the total amount of points you get. All that matters is the HL tests that you get a 5, 6, or 7 on because you’ll get credit for them.
