I haven't found it too bad so far (mind though that I only just finished the first semester). Yeah, I needed to spend a lot of time studying or practicing, and I didn't get to spend a bunch of time with friends during the semester. Sometimes the amount of information I needed to learn in one week was overwhelming, and some of the professors had strict standards. It also took a bit to get used to nursing school style questions.
But putting in the effort and the time made it easier. The professors were always willing to help or explain. There's a ton of resources I found to help me out. I was able to see and do some interesting things during clinicals, and I learned a lot. It wasn't impossible or breakdown-inducing or anything. (Now next semester when my programs becomes more accelerated... we'll see.
) I do think having a previous degree helped me because I already knew how I study and learn.
I should say though that I've always enjoyed school and have always done pretty well in it. So I know other people have a harder time or dislike nursing school because they don't like school, etc.
