To OP, I was in the same position as you. I had a torrid first two years of uni, and was actually suspended for a year. Many great schools don't have a minimum requirement for GPA. What you really need to show in your app is that you have changed and give them a reason for your poor performance (whether it be immaturity, wrong fit, medical issue, etc.). As long as the admissions committee can see that you've tried and improved on your past performance, you have a decent (maybe good) chance of getting in
