I received my ADN to BSN from Chamberlain College of Nursing. I was very happy with the program... here is how I would rate it.
10/10 - convenience (including applying, access to classrooms and contact with teachers)
7/10 - quality (i have to be honest, i just wanted to get a BSN behind my name at this point)
7/10 - Cost (they counted many of my credits from my previous Bachelor's and looking at other online programs, this was a very reasonable program)
They give a discount to Chamberlain Alumni of $300/class, which turns out to be about a $4500 savings, so before all of the additional costs, the program is around $24k for me.
I will be starting their FNP program in the fall. Completely online except the immersion weekend (like the other post stated, in addison IL). Practicums are found by you in your home town, so you definitely need to have contacts. With the FNP program, there are 5 classes of practicums which are different topics (pediatric, womens health, etc). You can use an MD or NP for the practicum. I'm not sure which program Scrubing77 is referring to, but you can do all 5 practicums at different sites, there is just more work involved with getting background checks, etc done for each site.
September '13 is the first cohort for the FNP program.
The advisors are readily available by email or phone with questions and if you just want to inquire, go to the chamberlain website and click on the 'chat' button.
