Calculus is not taught to everyone in high school. Many students only make it as far as precalculus and many more, even if they take calculus in high school do not learn integration. At the college level, many biology students do not take calculus. As far as calculus being a requirement for entrance into med school, in many cases I am afraid you are incorrect.

Most pre-meds do not have the time in their undergraduate careers to take a two semester series in calculus, especially if they need to also take remedial courses such as precalculus first, and many do.

Calculus, per se, isn't a requirement, but physics is covered pretty heavily on the MCAT. And last I checked, you needed calculus for college level physics.

Calculus-based physics is not tested on the MCAT. Or, at least, no calculus is required for the physics portion of the exam.

To my utter shock - I thought it'd be one of the last bulwarks against premed memorization. When I learned otherwise, it was sad to think that those students who flocked to non-calc physics (and floundered; the classes are of course curved) really would have a good shot at medical school.

Most universities have a physics sequence that does not require physics. A major reason this sequence exists, at least at the university that employs me, is pre-med students. Also, physics is not "covered heavily" on the MCAT.
