The public school system near Columbus Air Force Base and I attended for 3rd and 4th grades (taking 7th and 8th grade English and science courses) in the '74 and '75 school years.
For reading, worked through a box of SRA booklets in a couple of weeks time and then went to the library for the rest of the year --- mostly I was bored and coasted until my classes caught up, and even then, I was able to get decent grades w/ minimal effort.
Of course this all came to a head when I was a junior and the school system couldn't find a teacher for Calculus for myself and the couple of other students who wanted it which pretty much killed my college prospects, so aced the ASVAB, DLPT, and EDPT and enlisted.
