I think you have a good chance. Your OAT's are great and SCCO asks that you at least score a 300 in RC. Your GPA is a little low, but your OAT scores should offset that. Depending on your shadowing/volunteering, I think you have a good shot.
the only advice i have for you is make sure you have shadowing experience. it was definitely a topic during my interview. they wanted me to compare my experience working at lenscrafters (corporate) and at a private office.
also, just a heads up... my gpa is around yours and they basically asked me what happened and why i got the grades that i did. 🙁
I took a kaplan class for the OAT but that wasn't too helpful. I just pretty much studied an entire summer prior to the test. not much else that i can say that i did.
