No, but I have a BSc in psychology from my university. I didn't get into the clinical psychology program for the first three years (it's one of the hardest courses to get accepted into in Norway because of the grade average required), but I'm finally about to enter it now after a year of improving my high school degrees by re-taking some exams.
I am 21 years old. It flatters me that you say I'm mature, but I want to be humble and write that I definitely have my flaws and am simply working on them to become a better person :) It's interesting that you thought I was 35, though, considering my profile picture, ha-ha.
