Graduate school has been very good for me. There's a different format than undergrad. It's more of a seminar environment than a high school one. Undergrad is too much like the latter. I also am able to speak a lot myself, which I like. In undergraduate classes, I recall that professors would get impatient if you bogged their lectures down with too many comments. Grad school is a more level playing field. The professors genuinely respect your arguments. I was in class yesterday afternoon and I did a lot of speaking, and arguing with the professor. It was a very productive class. Also, I get useful feedback on my writing from people who are experts on the material. It's helpful for honing your craft. Additionally, I was uncomfortable in undergraduate classes, being more into the material than others and also much more knowledgeable about it, but now I am surrounded by others who share these things in common with me. I am happy with it. As for politics, it never comes up because it's irrelevant to most courses. Professors take far fewer liberties with class time than undergrad professors.
