- any other advice? -
I discussed it before, but I recommend keeping quiet when you think your young classmates are immature. You will, often, feel more mature and superior to them. It's inevitable. Or you'll just feel older because, say for instance, nobody remembers the Challenger explosion or that Reagan got shot. Just keep it to yourself.
And avoid about your life, career, or other experience as part of your class discussion, even if you think it's relevant. Watch when someone else does it - pretentious isn't it? Let the other old person take the fall.
You'll have opportunities to talk to with other students after class, and some will be interested in your life and career. The younger students don't automatically dislike the older students, just the ones who are arrogant in class. My classmates were really supportive and encouraging when I got married, and they are now that I'm having a baby.
Beer pong. At least once.
