I know it seems ridiculous, but it does take longer to get the ADN, then bridge to the BSN than it does to just go straight for the BSN. The big difference is price. My entire BSN degree, going the ADN route first is a total cost of $23,500. I am only paying $2500 of that because of scholarships and tuition reimbursement through my job.
I took all my BSN prereqs during my ADN program and only had 2 more classes to take this summer, after graduation. I have to take 11 classes during my BSN, all online and will go ahead and take a full 2 years to do it. The beauty of it is that I got my job, in a hospital, after graduating with my ADN and can work during the whole BSN program. I like that I will be 2 years ahead in on-the-job skills and experience. I didn't go into this whole nursing thing thinking I would end with ADN, so there weren't any surprises for me. It is what it is.
Good luck with everything. Remember that it's all temporary and in the end, you will be a BSN-RN. :)
