<p>I’d say the professor matters a lot. I seek out those that are supposed to be good, and haven’t been disappointed yet. A bad professor can make an interesting subject boring, a good one can just about make a boring subject interesting. </p>
<p>Remember something- not all professor’s styles may work for you, so what is “easy” to some (say homework is most of the grade) may not be for you (say all tests). Know what I mean? If you really care about GPA above all else, seek professors with styles that work for you.</p>
