<p>there is no need to major in all 3. you can major and double minor, or double major and minor in one. if you want to do research, what type? if medical i would major in biochem and minor in physics. have you done serious research? if not then try physics research one semester, chem the next, and bio the next. see what you like best by the end of soph year and major in it and take lots of classes in the other two. some schools offer biophysics, so try majoring in that. i honestly cannot see why you want to tripple major. i would like to major in one of these sciences too, but two or three seems overkill. </p>
<p>to answer your question, any top university (even yale) will have a very good science program. MIT will have almost the best internships for undergrads tho. if you do want to tripple major i think MIT's curve will be too intense for your heavy courseload.</p>
