<p>arpesh,</p>
<p>You're waaaay to early in this process. It's good to be thinking about choices now, but you'll be in a much better position to gather information when you're in college, especially if you attend a research uni that has MD/Ph.D. faculty. </p>
<p>The KEY criterion for admission to a md/phd program is undergrad research experience, so that should be your short term goal. As soon as you've decide where you're going next year, start researching the faculty. Plan a visit to the campus to visit faculty that might consider undergrads in their lab (not all will) and start working to find a lab home. </p>
<p>The research experience will do everything to help you decide a course. Some love the experience, some don't.</p>
