I won't start the actual ADN program (the NUR classes) until August 2012. I don't know anybody that has been through the program before but I have never heard it being "impossible". It will probably be challenging and time consuming and involve lots of studying, which I have prepared myself for as much as I can. I don't know what the pre-req classes are like at Mitchell since I took the majority of those at Rowan Cabarrus Community College. I made all A's in my pre-reqs. I would recommend getting all of your pre-reqs out of the way before even trying to apply for nursing school.
The only advice I can give you to do well in the pre-reqs is to study, do the assignments in a timely manner and show up to class. Have some form of communication with your instructor and with your other classmates. It made going to class enjoyable and I looked forward to going. I wouldn't recommend taking an online class unless you ABSOLUTELY have no other choice. I feel that I have to do a lot more work on an online class. I made an A in the online class that I took, but I feel that I wouldn't have struggled as much with it in a standard on-campus class. Another thing I have experienced is that evening classes (after 5PM) were a lot better classes to take. They seemed a lot more laid back and not as full as the day classes. The students were different too in that most of them were working adults and not kids straight out of high school. So the atmosphere and conversations were more serious and you feel like you are in college and not back in high school. Also the instructor is normally a part time employee with the college and has a full time job during the day. They understand that students have to work and they are more laid back about assignments and homework. Day classes are okay, I just felt like I was back in high school in some of them.
The classes I enjoyed the most were Microbiology, Psy 150 and Psy 241. Microbiology class will change how you look at everyday things. I actually became a germaphobe for a short period of time during the class, and still am to an extent.
That is all I have for now. If I think of anything else I 'll let you know. Good luck in your classes!
