No ECs.. Are my chances ruined?

"Really? I never knew that the percentage is so low. Both of my parents went to college then immigrated to the US to have me, which makes me a first-gen American/second-gen immigrant (sorry for the confusing terminology). "

Yeah, it’s pretty low, maybe even lower in a field like data science. You would not be considered a first-gen. Find out if your high school has Naviance or a similar tool, and how previous applicants in your high school have done with OSU, if that’s your first choice in-state. OSU’s acceptance rate is 55% for women and given you’re in state, could be a little higher for you. The uw gpa is still low even though you do have rigor.
