I am a student who will go to Cam or Ox to continue my Phd in Engineering
I am also always very interested in the world uiversities ranking ,
at the beginning, I am also confused by various ranks,but in this days I found a remark ,not a rank , by a nobel laureate whose major is physics .
He said there were top7 in the world
1.harvard 2.stanford 3.yale, 4, princeton, 5.UCB 6.MIT 7.CAM (same level)
the second level is Ox, Caltch, Tokyo ,chicago and many other US universities. he especially said that he was very disappointed with Oxford in that Ox is much worse than the above seven, even no better than those in the second level.
His opinion is purely academic and especially said in every field Cam is a little worse than Harvard but at least the same as the other first level universities.
And I must admit that the atmosphere in Cam and Ox is unique, In my opinion and dream the life in University should be the same as Ox and Cam. You can find that many American students who graduated from Harvard,Yale still come to Oxbrigde to attend a Msc course. Such as Clinton, why? They just want to feel one kind of atmosphere, tradition ..., the life between oxbridge and Harvard is totally different.Some people are suitable for this kind of life but others are not. Remember, the most valuable achievements you got in the university is not from the university's classrom but your life,your friends,your experience.
I just got my Beng degree so my feeling is my truth thinking. In the Bachelor level, the academic content is so naive if you can continue to a phd. And many valuable things you study is in the work and fron your friend.
