I didn't miss any point and just asked a simple question.

It is great that the Talmud teaches all those different things. Lets just pick a subject, math. Do you believe you can learn as much about math from the Talmud as from a HS math class?

On a high school level of Talmud vs. high school level advanced math - no.

However:

1) It's easier to teach math later on than it is to teach critical thinking and thoughtful analysis. Furthermore, most colleges have college classes that cover both basic high school math as well as more advanced high school math. This is an important point in 2 ways - it shows that many students outside the yeshiva world are entering college without a firm grasp of these concepts, and it also shows that even if one did not get a strong math education prior to college, that need not hold them back.

2) A solid foundation of basic math, including fractions, is more important for most people than the advanced math of high school. I will accept that the problem with this perspective is that a small number of students excel at more advanced math, and without the exposure to it, there's no way for them to know if they have an aptitude for productive and lucrative careers in those fields. While this exposure can come later, I can see the advantage of earlier exposure.

Things like math and reading aren't just a bunch of facts you can gauge on a standardized test. They're skills that need practice.

Skills that need practice require homework, studying, and then you gauge how well the students have acquired those skills. Generally, the accepted way to do so is on a standardized test of some kind, although as a former teacher I can debate that as well.

Recommending more hours of classes despite students demonstrating proficiency in a subject seems like a waste of time.
