How many credits have you taken already? If you took, say, 90 credits worth, then, no, you can't achieve a 3.5. If you've taken 10, then yes.
But, I assume that since you're close to graduation, you're somewhere in the 80-100 credit range, so, no, it's not possible to achieve a 3.5. You probably won't be able to reach 3.0 even if you get an A in all those classes. Sorry to bear the bad news!
