Chemistry

My son got a 5 on Chemistry AP. He wants to major in comp. sci. and possibly minor in chemistry. Should he take the 8 hours of chemistry or take the course to get a good grade?

My son took the credit because it is a good amount of class work, and there are other classes that do not require a great deal of work to make a good grade. Minor in chemistry aspect? I still would imagine he has his foundations and could continue on with the next level of classes depending on what he was interested in.
