Not all of the sciences keep you in math. Chemistry and biology majors often don’t take anything beyond calculus III, and many of them don’t even take that. Chemistry majors often take linear algebra and differential equations, especially if they intend to take physical chemistry. Biology isn’t a very mathematical major though. It can use a wee bit of calculus to model population growth and decline, and it uses a fair amount of statistics. However, math isn’t really a part of the “toolkit” for biology in the sense that it is for physics.
