I actually got very good grades in high school - oh soooo long ago - with minimal studying. I was on the, wait for it, Debate Team - which was rather "geeky", and in the school choir.
But, I had a diverse circle of friends. Some shared debate and/or choir, some were athletes, a few in Drama, varied races, and some just sliding by barely passing. We had interests in common outside of grades and school and many of us still keep in touch.
I was not the best student in school - I remember those! LOL The girls who always made honor role, received the awards and teacher's accolades - I never felt intimidated by them - they, honestly, were very nice girls and friends also.
So, no, I didn't limit my friend ships or social interactions to student's with the same GPA as I had. I think the more types of people we get to know, the more we expand our horizons and increase our acceptance of others.
Good Luck and God Bless
