Mixed bag.
I remember the few good teachers i had fondly, although, againts my school's best efforts, i do say i turned out smart.
My classmates... Eeh, the few friends i had, we grew more distant every year due to our interests drifting, so i became the loner of the class, my class was very divided, to the point that we broke school traditions cause we couldn't get along enough to plan the events and whatnot (in my school it was custom for the Seniors to be in charge of the events), we don't do reunions nor add each other in Social Media either.
I do have some stories, but overall, i'd say that my experience was average nothing especial.
I enjoyed college far more, met cool people, and i am still in contact with my best friend from college.
