<p>Are there certain requirements for high school students to have, like taking a certain number of science classes, in order to study pre-med in college?</p>
<p>It depends on the college. Also, most colleges don’t have a pre-med major.</p>
<p>For the usual pre-med course work (pre-med is not a major and can be done with any major):</p>
<p>High school chemistry and physics are commonly recommended prerequisites for college chemistry and physics.</p>
<p>High school biology presumably helps with college biology, even if not listed as a prerequisite.</p>
<p>High school math through precalculus and trigonometry is the typical prerequisite for calculus (and perhaps statistics) in college.</p>
<p>High school English writing courses are typically needed to prepare students for college English writing courses.</p>
<p>More rigorous or AP courses can help with the preparation, although medical schools typically do not allow substitution of AP courses for college courses (although using more advanced college courses if one does skip introductory college courses with AP credit is typically allowed). Note that dual enrollment or other college courses taken while in high school and their grades do count for medical school application purposes, while AP credit does not.</p>
