As for the teaching style, British universities are a bit like expanded free high schools. Oxford and Cambridge even have lawns that professors can step on but students can't. I can see that the level and academic level are very important, which is a bit old-fashioned. American universities are freer and give students more choices. Professors and students are also more friends.
Under the strict system, the standards of Cambridge and Oxford are also declining. It can be seen that the wind of freedom in the United States can promote progress in all aspects.
