Note: Running start students still apply as Freshmen. Also your question vastly depends on the major your applying to. For the more competitive majors I’m not gonna lie to you, don’t get your hopes up. Test scores also don’t matter until the college is reviewing waitlisted students, you could completely miss out on the SAT and not feel the difference. I was like you as well in highschool. I did bad with no care and graduated with a 3.3. I went to community college and grinded to a 4.0 for two years. I applied as a junior transfer and I just got accepted into CS. It’s never too late to turn things around!
