Is it harder to get into Law School?

Hello,

I'm just out exploring several graduate options and it seemed a little odd to me that top law schools had higher average GPAs than top medical schools. Is it harder to get into law school than medical school? Or does that simply reflect on the undergraduate classes taken?

I'm originally a pre-med and am still fostering hopes to attend med school. As a result, I've taken several pre-med required classes. If I later decide that law school is the path for me, would my lower GPA as a result of having taken several difficult science/math classes ruin my chances (i.e. Orgo, multivariate calculus, biochem, etc.)?

Thanks!
