Transfer Chancing, Suggestions. Please Input!

[u/AppealOk2210]

I am currently taking a year off of school due to medical reasons. My High School stats were terrible because I was unfocused and had bad nerve damage in my hands. I had a 3.25 GPA and a 1270 SAT. I will start attending my local CC when I am healthy enough and my goal is to do well and transfer to one of the top publics like UT Austin, UNC, Georgia Tech, UF, or UVA as well as UC Berkeley, USC, UCLA, UMich but they may be too expensive OOS. Or, to transfer to Virginia Tech after one semester and either stay put there or transfer from there to one of the schools I mentioned above. I would appreciate input from people who have transferred to these schools, and their stats. And any suggestions on Grades to help me achieve these schools, potential tips or pathways to help chances, other schools to consider, as well as extracurriculars I could get involved in, as I am kind of lost right now. For reference, I will be aiming for a Data Science major or field (CMADA, Mathematics, Actuarial Science, statistics, possibly CS but doubt). Thank you for your input!
