Chance Me!

9th grade GPA- 90
10th grade GPA- 85
11th grade GPA- 89 (currently)

I am a junior in high school, and wanted to ask you guys what are my chances of getting into University of Miami…
Currently it is fourth quarter of 11th grade and my gpa stands at a 89. Though, I heard that colleges want to see improving grades throughout the year, from 9th grade my grades were great, then 10th grade my grades dipped and junior year I am improving better. Plus I attend to do great on the SAT and ACT scoring above average. Do I have a chance of getting into University of Miami?
Plus - early action and if I tour the college.

Is a 90 a 3.9 GPA, 85 a 3.85 GPA, etc…?
