In my case, I was a product of the New Math curriculum, later despised
by the backlashers (fundamentalist back to basic types). I scored
1490 in the SAT and placed into Honors Calculus under Thurston, none
the worse for the experience.
The honors classes, the good ones, still use those "New Math" books with the sets and the bases. Those are many of the students you see streaming into Google, Apple, Facebook etc. I interview a lot of people and you can tell when they have had the "experience".
