This rings so true. I have a 138 IQ, and felt the vast majority of school was such a waste, nothing challenged me. I took all the AP classes I could which was something, but by my junior year of highschool I just enrolled in classes at the junior college and started going there instead and nobody did anything. I still graduated highschool at the normal time, just with my first year of college already completed. I feel like I could have been so much further along had anyone enabled it.
