1st semester grade get a B

My D is going to apply RD Olin business. She is so nervous that her 1st semester AP cal is going to get a B.
Her current stats are:

sat 1540
act 33
gpa 3.93/4

lots of EC’s
good recommendation letter

She is also an athlete and already verbal commit to WUSTL and coach said will support her.

Will this B hurt her chance to get in Olin even with coach’s help? I heard Olin is very hard to get in.

1 B is not going to make a difference if the rest of the grades are good and the rest of the application looks good.

Tell her not to worry. A B is ok. Even a C when you have pushed yourself to take many difficult classes Can be ok, if the HS has a good reputation.

Washu is D3 so idk how much pull a wustl coach will have but her scores seem to be in range and as long as her gpa doesn’t drop below a 3.9 I think her chances are pretty good.

Thanks for the comments
