<p>Well I’m currently in Multivariable Calculus at my high school (I took BC calc as a soph and ap stats as a junior) so I could potentially drop that course, but then I wouldn’t have a math class my senior year.
Plus, I think such an advanced class like Multivariable Calculus will look a lot better to Harvard than a 4th year of science.</p>
<p>I could take a non-AP level 1-semester class such as Medical Microbiology or Pathophysiology in the second semester of my senior year however.
This would give me 3.5 years of science.</p>
<p>Would a school like Harvard like 3.5 years of science with one of those courses? And is taking 4 years of science really that essential to Harvard?</p>
