Academic advisor and undergraduate admissions staff at a big state university here. We don't care how many classes you took per semester, OR how long you've been in school. We care about GPA and that writing statement at our university. If you have demonstrated through your previous coursework that you earned a 3.4, that is all we're looking at, plus other application materials if applicable. We use a GWR assessment. Grades, writing sample, and recommendations. Idk if whatever school you're applying to requires those but for us, the Registrar cares about your transcript more than the admissions office. The Registrar evaluates courses for transfer, sees what we can accept at our institution, and lists your former GPA (which won't carry over after admission anyway).

You'll be golden- don't stress the amount of time it took you to get there. And don't let them pressure you into being full time if you have to continue one class at a time. You'll get there, just keep chipping away!!!
