Transfer application

Hi! I am a community college student who really really wants to transfer to unc. I had a very poor high school performance (2.5 gpa), and in my first semester of community college I got a 3.3. I know to apply I need a very competitive gpa, so improving that is my main goal, but I am seeking out recommendations for other things I can do to make my future application stronger! I volunteer at a nearby animal shelter at least twice a month and have earned 20 volunteer hours so far, and I work part time.

I am in state and plan to major in psychology if either of those pieces of information are helpful at all.

I'd appreciate any tips! Thank you!
