Racing to calculus in high school so that you can repeat it in college?

The kids I see getting into Berkeley for engineering were two years accelerated in middle school, then went to a high school with the quarter system where they accelerated even more, ending with two years post CalC BC math at minimum.

Not really believable overall, since that would mean that UCB students would largely have completed the math requirements for most majors while in high school. Next fall, there will be 950 spaces in MATH 1A (first semester single variable calculus), 697 in MATH 1B (second semester single variable calculus), and 962 in MATH 53 (multivariable calculus). If so many UCB students have already completed these courses in high school, why would there need to be so many spaces in these courses?
