So, I was originally planning to get a B.S. and to major in Biology and minor in Geology. But, the primary college I was looking at (which is actually a good school for science) only offers a B.A.? I don't quite understand how you can get a Bachelor of Art in a scientific area. Will having a B.A. make it harder to get into and do well in grad. school? Should I still go with that school as a consideration? Should I still go with that school as a consideration?

This is a UK based site as you know Carrie. Here it is very unusual to get a BA in a science subject (unsurprisingly). We can't comment on US colleges nor how the degree might be viewed when applying for postgraduate courses.
