<p>I am a freshman at Vanderbilt, and I want to take some classes at Yale over the summer because the summer program at Vandy are longer than the ones at Yale (Yales Summer A session is only 5 weeks, whereas Vandy’s is like 7 weeks). My question is how difficult are the classes at Yale’s Summer School? I want to take intro to physics and an econ class. I am pre-med, so doing well in the intro science class (Physics) is VERY IMPORTANT.</p>
