Difficulty to maintain a 3.3 GPA

How hard is it to maintain a 3.3 GPA at U Mass Amherst?
I know that it also depends on major but I am unsure on what I want to do and want a general idea of how hard it would be to maintain a 3.3 GPA

If it helps for comparison I have a 3.5 GPA in Milton High school and am going into my senior year now.
Would i be able to maintain a 3.3 GPA?

No one here know you or your capabilities. We don’t know your major. We don’t know your work habits, or your play habits. We don’t know how you’ll react to being away from home.

In short, I think the consensus will be " we have no idea."
