More than likely Biochemistry is a concentration of a Chemistry degree. It is also more than likely that you will have to take most if not all of the calculus classes to obtain such a degree. I'm sure you know this already, but let me remind you that you don't need a certain degree to get into pharmacy school. You just need to complete the prereqs. If you want a degree but you are more focused on pharmacy school, maybe you should avoid one with so many maths. Also keep in mind that Pharm Schools really only care about your prerequisite science/math gpa, so keep those courses high and you'll be good.
I'll be graduating with a degree in Biology with a Concentration in Molecular Biology and a minor in Chemistry before I go to pharmacy school next fall, God willing. It's like a sister to Biochem, but it's not as difficult and you take less pointless math/science courses that could end up hurting your GPA. You take nearly all of the courses required for pharmacy school, though, so that's a plus. The only negative is that it's not as marketable as a BS in Biochem, but if you are planning to go straight to Pharmacy school and you are a strong candidate, that shouldn't really be a problem.
Good luck pal.
