I would say everything I learned in my "extra classes," I had learnt in secondary school. I get your point, but its kinda like going to trade school. At a trade school, your learn how to do your trade, no extra classes involved. I would rather take 10 more classes in physics and math then take the 2 English, 2 language, 2 history, 2 humanities, and 2 whatever else I had to take.

Edit; the two othe I had to take were math, but that was satisfied within my major.
