Agreed. My daughter was out of high school at 17 and should graduate from college by 20.
I graduated in June 1976 and turned 20 in August 1976. High school graduation was June 1973. It was good to be a 16 year old high school senior with a driver's license for a car. I rode my Honda CB175 to school starting at age 15 1/2 with a permit. Graduating early from high school and college just requires the tenacity to attend every summer school session offered and reap the maximum number of credits allowable.
