My chances of getting in for Computer Science

Hey Rich,

I ended up getting a B in AP Computer Science and B in AP Calculus due to family issues will this reduce my chances of admission. Out of the 44 coursed I took I got B’s and B+'s in 4 of the courses. AP Calc and Comp sci are 2 of them. How can I communicate to colleges that the reason I got those B’s were because of family issues.
