I think it depends on the type of person you are. In undergrad, lots of things were boring because it was just a class I was taking that had no real significance to anything in my life. Turkish-German Lit, German Feminist Lit, etc....while I got to read some interesting things, was just a grind after a while. Granted, I'm only 4 weeks in, but not a day has gone by where this material hasn't solidified into a greater understanding of something. Now, is sitting there and memorizing anatomy or questions fun? Not really, but seeing how that knowledge is applied, reading things and suddenly understanding and constantly expanding my knowledge base for things I am much more likely to know IS pretty cool.
I'm sure there will be courses I despise but I'll probably find a way to have things make sense there too.
