Can you try again?
For next year I assume? Sure.
But, would you expect things to be different? What can you do after you graduate to substantially change your chances? Instead, why not consider CC and transferring? Then you start with a clean slate.
You can’t change your GPA or your rigor. So, can you raise your SAT/ACT scores? Can you do 21+ hours of EC w/Leadership and 21+ hours of work in your major? Those are the only things that will make a difference in admission next year.
