i had a 3.4 gpa in HS, I graduated this year. I applied to mostly Boston area colleges. I got into: Northeastern, Simmons, Umass Amherst, (which isn't really Boston area, it's a good two and a half hrs away) Saint Anselm (in NH but near some big hospitals and an hour from Boston) Fairfield, UConn, UVM, UNH, Mass college of pharmacy and health sciences and Drexel (in philly)
Of those, the only ones in Boston are Simmons, Northeastern and MCPHS. I would recommend applying to those ones. Some other ones to consider are Umass Boston, Curry, Endicott, BC. Northeastern has an amazing program, but I chose not to go there due to the price. A nursing degree is a nursing degree and I wasn't going to pay an extra 120k just for a name. Its also right next to Simmons and MCPHS, which are right near a lot of the big hospitals. So I would definitely consider those ones.
