I think you should emphasize that you'll be around for 3 more years. It shouldn't be hard to work into conversation. The chapter members may study up on PNMs and may already know you're a junior and even bring it up, so you can talk about it then. If they have no idea and ask you, "So what did you do in high school?" you can reply "Well I am a junior, I transferred, I'm a double major going to be around for 3 more years blah blah blah" and then talk about what you've done since college.
