Psychology is nothing like I was expecting it to be, personally. I thought that the entire course felt really outdated, and the subject matter was relatively boring compared to how interesting and relevant psychology can actually be. There was tons and tons of papers every lesson, and keeping them well-organized was a lot of work, not to mention revising from them. Other people, like yourself, may find having lots and lots of papers to revise from enjoyable and easy, I found it inconvenient and stressful, myself.
The teachers can also be terrible, but I suppose that's the same for a lot courses, I suppose they're only trying the best with what they have available. I personally wish that I went for Sociology, since that's what my friends did and a lot of what they did sounded really interesting and generalisable, where-as Psychology was a lot of Milgram, Freud and Pavlov.
Overall, it's a lot of work, and if you're willing to put in the effort to keep your stacks of papers organised, then I say go for it! Good luck.
