<p>I plan on majoring in science, either bio or chem, and at my school you have to take 20 required courses to get a degree. I am a rising sophomore, and I have taken four out of 20 so far, and I have taken three non-science courses. I hope to apply to med schools after my junior year, and I think I will have taken just two more non-science courses by then. Is 5 enough? Or do I need more?</p>
