I am in Sinclair's LPN-RN bridge program right now so I thought I'd give you a few thoughts on it...
If you bridge, you go directly into NSG 132-133 which is the state mandated transition class. It is 1 quarter for these two classes. If you bridge, you essentially skip NSG 121, 122, 123, 124 I think so it looks like you are saving 2 quarters.
The last I heard, it was nearly a 3 year wait to get into the regular nursing program
at Sinclair and that is after you get all the pre-reqs done and get on the list. Though they say there's no real list for the bridge, there really is. I already had a degree but still needed a few classes to qualify for this unofficial list. I got those done in 2 quarters ( going part time). I still had a few classes that I needed to take which took up another 2 quarters (part time). I lucked into the bridge program just in time. Essentially, it took me 4 quarters to get in.
I don't know that any more people fail out of the bridge program than do those who go the traditional way. Of the 9 that I started with in my bridge class, 7 of us remain. One didn't make it. The other would have but had to hold off school for other reasons. Is it tough? Yes, it is much harder than PN school. Is it doable? Certainly.
I don't think it would be any harder bridging than going the regular route. You do miss out on some things skills wise but they're not hard to catch up on. Sinclair has one of the best ADN programs around with a really high first time NCLEX pass rate. The program overall is tough but that is as it should be. There are instructors that people tend to avoid but I have no complaints about the ones I've had thus far. I am seeing the end of the tunnel now and have only one class quarter and the preceptorship quarter left.
NSG 220 for most people seems to be the hardest class and you have to take it regardless of whether you go through the traditional way or bridge. After 220, you do 2 classes per quarter (4 hrs each) and they are each 5.5 weeks. For instance, last quarter I did cardiopulmonary the first half of the quarter and psych the second half. This quarter I had neuro/ortho/uro the first half and now I'm in OBGYN/L&D. It's a lot of information in a short time but even being a much older student than most of my classmates, it's certainly doable.
In addition, Sinclair's tuition is really low compared to any other school around. I don't live in Montgomery County so my tuition is about double but it is still less than $100 an hour! Let's see, a fantastic nursing program at an affordable price (especially considering I have to pay it all out of pocket).
I would suggest trying to get all non core nursing classes out of the way before getting into the program if possible. It will make life more bearable in the program. This is especially true for classes like Human Physiology (if you bridge you take this instead of repeating all the A&P classes) and Pharmacology. You will hear horror stories about the pharm instructor but go in with an open mind. If you do your work before class and study, you'll be fine. It is hard but you will learn a lot from him and he's not as bad as people say.... actually, I liked him.
Good luck whatever you decide to do!!!!
