<p>I think most majors require at least 30 some classes; I know engineering requires 36. Most students take 4-5 classes a term. I have no idea what you’re trying to ask in your third question. Your fourth question is incredibly general (classes start and end at all sorts of times!). Some classes are only 50 minutes, many more are 80 minutes. I’m a graduate student, so I study all the time because that’s what I’m paid to do. Getting an A is pretty tough in graduate courses, not so sure about the undergrad ones. Medical schools are aware of what schools inflate grades and which ones do not, so it probably won’t hurt your chances too bad if at all.</p>
