Hi and Congrats!
I currently attend Forest Park and will be graduating in Dec. I've never attended Meramec so I can't say which one is better but Forest Park is awesome. To me, nursing school wasn't necessarily hard, it was different. Its more than just memory, its how to apply the information to different situations. On a test you will have two right answers and two wrong answers, but what is the BEST answer. If you are having a hard time, dont be afraid to meet with the faculty, they are there to help you! They will find out what your weaknesses are. Also meet with the retention coach if need be.
Be prepared for clinical work! It is very time consuming! Be prepared not to have a life. My life consists of school, work, clinical, and home and not necessarily in that order. Hope this helps. You'll do fine!
