macomb community college, oakland community college are both competitive entry- no waitlist, based on how well you do in prerequisite courses, and entrance exams. Not sure about most of the others, though the standard average seems to be anywhere from 2-4 years- There are other programs and colleges that offer RN, - oakland univeristy, rochester college, davenport, ITT, etc... I would go to each schools
website, check their accreditation and admission policies...
Personally I chose baker college, it is a competitive entry program, and still waiting to see if i will start in the fall or not.
good luck in whatever you choose to do.
