I’d be shocked if you didn’t at least get an interview at Auburn. (War Eagle fellow Tiger!)
I agree, you lack diversity in your experiences. However, the experiences you do have will set you apart and that’s good!
You didn’t mention all of you LOR, but those are pretty important as well.
If by some chance you don’t get an acceptance this cycle, keep going! The only thing that could make your solid app better is more experience.
