RN ADN BSN program experiences

Is there anyone out there that can tell me opinions/ experiences between ADN, BSN, and RN-BSN prgrams and also in terms of level of difficulty? I kind of always wondered if ADN programs were more difficult than BSN programs because of the academic preparation and the time frame being ADN programs have a year or 2 less to prep you for boards....and how difficult are the RN-BSN programs? I was wondering if they were more lax because you've already passed your boards so that goal is out the window?
The content in an RN-BSN program is totally different from the content in an ADN program. It's not "more lax", it's just theory, research, and writing papers rather than the application stuff you learn during the ADN program.
I'm in an RN-BSN program now- each program probably varies but the program that I'm in meets one night per week. We have no tests, just lots of papers to wrtie, usually some kind of big paper a week. Heavy on the research and APA format. The only course similar to anything in the ADN program I was in was my Public Health Course because you don't get that in an ADN program. That's the only one with a clinical component that I'm finishing up now. So, it's actually easier I'd say, unless you don't care for writing papers.
