General Advice for UHCO

Hello All!
I am about to finish my 2nd year in college.

-Nutrition Major
-My gpa: 3.25 (planning to try my best to raise it to 3.4/3.5)

I would love to go to UHCO because I currently go to UH and I was born and raised in Houston.

I have a few general questions.

1) When is the best time to apply? Next summer maybe for early action (July 1st)

2) When is the best time for me to take the OAT?

3) What GPA & OAT scores would I need to have in order to be competitive?

I appreciate your time!
Thank you
