I do not know about the specific schools in your area, but what I write is from the schools I have looked into in my region. ADN is 2-3 year program with pre requisites and then nursing courses. It is usually completed at a community college/tech school and more affordable, as well as quicker. BSN is a 4-5 year program with the same bio pre reqs (usually), although some may or may not have one extra science class, such as chemistry or nutrition. There are more liberal arts courses for a BSN, so you take more than the standard english, math, sociology, and psychology. Also, usually a BSN has a couple more nursing courses than an ADN. Both are clinical heavy, but BSN is a lot about theory too. Because the program is longer, you are able to take these "theory" nursing classes. One BSN program I am looking at has you take one nursing research course as well as 2 nursing electives. The ADN program at my current community college does not offer that in their program because their program is shorter. I am still taking pre reqs, but I have read that actual nursing school is not just the memorization of information (like anatomy is), but rather how you apply what you have learned. I have never enjoyed biology, but have found my pre reqs fascinating. I have taken basic bio, microbiology, nutrition, chemistry, and now anatomy. With the exception of chemistry, I have enjoyed all. Do NOT rule yourself out because you do not think you will do well in biology. I did that and wasted time/money for one year pursuing a different major that I did not enjoy.
