Hi, Kate Rushton. It's interesting to see how many projects you've responded to and how many comments you've left on different challenges. Your questions seem to come from a relative place of privilege. What do you mean by "more mature students" or as you put it, "career changers"? By Trio's description, it seems as if they equally set up all students to be career changers and leaders.
Lastly, have you ever ridden the red line throughout the Chicago neighborhoods? Are you aware of the violence hundreds of thousands citizens witness every single day? I'm not sure if your questions come from a place of sincerity, but rather from a place of self-gain through the "point system" here. Take care.
