I don't remember it being particularly difficult to get accepted. The most difficult part was coordinating the application and getting my transcripts to the school. I used the NursingCAS website for the application process. I actually had to take Health Alterations and Pharmacology at TAMUCC after I applied. I took them at a community college, but they wouldn't accept those as they were not upper level classes. I had to have my application in by October 2014 to begin in Summer 2015, but I didn't take those two pre-reqs until Spring 2015. So it is possible to have applied and then take pre-reqs. The way the recommended schedule is set up is you take about 3 classes each semester, for 5 semesters straight (including summer sessions). So, since I started this summer, I will be finished by December of next year (summer, fall, spring, summer, fall). This semester is 13 hrs, fall 2015 - 12 hrs, spring 2016 - 12 hrs, summer 2016 - 9 hrs and fall 2016 - 13 hrs. This semester is especially hard for me as it is a summer session and we only get 10 weeks to finish the same classes students in the fall or spring semesters would have 16 weeks to finish them in. Normal full time summer session is 6 hrs, so you can imagine. It's been pretty rough, so far, but I figure if I can get through this semester without drowning, I should be okay. As I stated before, this is a recommended schedule. You can take less per semester, it will just take you longer to finish the program. Also, if you stay on track with the recommended schedule, you are guaranteed a spot in the next classes, so you don't have to rush to register for them. However, if you fail a class, you are not guaranteed a spot in the next semester and you have to retake the class.
Hope this helps!
