@mystery-ak My son, in high school, which is in the NASA area, south of Houston, took advanced math, chemistry and English, graduating in the early 1970s, was admitted early to Rice University in Houston, and they only take 500 new students a year. His SAT score was so high, he was automatically made a member of MENSA at Rice. In the summer before Rice started, he took two "place out" tests in English and History and placed out of both, and was put in advanced Chemistry and Math then. He could start his degree choice courses instead of having to take regular Freshmen classes. His major was Space Physics/Astronomy.
I graduated from high school in 1951. There were no school counselors then; no one to advise you. Took courses in the summer at Kilgore Jr. College, then went to East Texas University in the fall (now is A&M at Commerce), and had to take tests. Had to go to an advisor for him to discuss my results. Went to see him and he said, "You can take anything you want, I don't need to talk to you." I was out of there.
