@bitznbatzn I do think the limits of the French system should be known. Of course, I do not want to disparage the French system, in fact I respect it a great deal.
I hold Cambridge in very high esteem, indeed I think oxbridge offers the best undergraduate experience available anywhere for the right student - it is better than Harvard imho, where I was a student. We are going to my daughter’s graduation from Cam on Friday. She worked incredibly hard there, enjoyed it as well as had some crises. It was transformational, we couldn’t be more pleased with how she has grown.
At any rate, it sounds like you have some wonderful options, I would love to know what you decide (message me if you want when the time comes).
