Well, it may not be a resume credit, but I'd say "develop relationships with members of the preferred gender" and wait until you get into upper division classes to do other stuff.
You could also join the local stock trading club/team. But at this point you probably don't know R and statistics, which limits your scope, at least when it comes to quantitative portfolio construction. So I'd concentrate on the suggestions from the above paragraph. With luck, life is long and there are many paths.
