My GPA is not that high at all, like 3.3 maybe, but I have a lot of work and volunteer experience and I was a research assistant in my third year. But I came straight to university after college, completed 5 years of university (BSW and crim degree) and got accepted to Western's advanced standing MSW program! It depends what the school is looking for, it's definitely not all based on GPA!
Good luck to you! Where have you applied?
