The GPA requirement for all of the CT CC nursing programs is is 2.7 however they base 50% of your ranking on your GPA. Here is a link for exactly what is needed in order to apply to any of the CT CC programs. Hope it helps.
They (the CC's) fill 75% of their seats with people by rank, the remaining 25% are selected randomly from the rest of the applicants. It is possilbe to get in with a 2.7 over someone with a say 3.5. Best thing to do is just keep your GPA as high as you can so you might possibly rank higher and end up in that 75% of the applicant pool.
And yes, (not me personally) but I do know of CC students who had the bare minimum GPA and got in. They obviously were in teh 25% of the pool selected randomly.
