I know two CDB scholars and they could not be more different, other than the fact that both are bright. One is very precocious in math, the other has a talent for visual arts. One is extroverted, the other is more introverted. One is male, the other is female. Their class and racial backgrounds differ. Yes, it’s a very small sample, but the takeaway point is that it is hard to generalize.
I agree with the advice that has already been given - put forward your best, authentic self and see what happens!
Good luck!
