The fact is that we will never really know the truth about the Casiraghis' university cursus. I am sure that Charlotte didn't finish her studies in Paris, that she has no degrees. But newspapers have another theory because they have to show a smart image of her to sell more.
I don't know about Pierre: he's very discreet, Boconni is sure because it is where he met Beatrice.
I don't know for Andrea. Did he finish? He never talked about it.
As they have no official role to play, Monaco Palace doesn't have to tell public what they do (as Clarence house does for Harry and William). That's why Casiraghis' degrees is an endless subject of discussion.
As Charlotte is concerned, I am sure of what I say, because - and I already explained it on this forum, if I remember well:
1. She studied for 2 years at Fenelon prepa;
2. She failed ENS.
3. As she failed, she went to Sorbonne to study philosophy, and that's the moment french university laws have to be mentionned:
- in the PAST: different degrees (DEUG = 2 years; LICENCE = 3 years; MAÎTRISE = 4 years; DOCTORAT = more years).
- NOW: there was a big "reforme" at the beginning of president Sarkozy's reign. We have less degrees now than in the past (to have the same as the other countries of European Union) (LICENCE = 3 years; MASTER = 4 years; DOCTORAT = more -
link to the official explaination of this reforme by french government here, but in french).
This reforme was applied during my second year of DEUG. At the end of this year, I had no degree, and I had to study one more year to have a licence. This was the time Charlotte was in her 2nd year of prepa. This means that when she arrived at Sorbonne, she was accepted directly in 3rd year, which is normal. But France didn't gave her any degree, because DEUG wasn't anymore: she sould have finished her 3rd year in Paris to get a LICENCE. This year she met Alex, she partied more and more (maybe discovering how free she was, at 20, prefering having fun with her friends rather than studying night and days for a licence - that was the time we saw the only pics of her a bit drunk) and she didn't go anymore to the university. Some students said that at the beginning of the year they saw her, and then she disappeared. And Charlotte herself said she gave up her studies during her 3rd year (in the Vogue interview I think).
This is a long post, to explain you that when I say that Charlotte doens't have any degree it's not an accusation, but it is the result of a long reflexion about what we know about her during these years, about my country's university system, and about my own experience. I'm not a Charlotte-hater, just a truth-lover.
