Chances?

I’m applying in state to MSU in the fall. I had terrible grades my freshman and sophomore year, but good grades my junior year and a pretty good ACT score.

Freshman GPA : around 2.8
Sophomore GPA : around 2.5
Junior GPA : 3.4 first sem 3.6 second sem
Cumulative GPA : 2.9
ACT : 28

I plan on having even better grades my senior year but i fear that may be too late

Your act is good, but the gpa is a bit low. If there was a major reason for lower grades, let them know. Otherwise you have about a 65-80% chance
