So I called them this morning and got a nasty surprise. My application is not valid. Reason: They do not recognise my (french) Bachelor's degree, even though only a high school diploma is required. It needs an equivalence statement... I've checked, it takes ~4 months to get it done, so it would have been utterly impossible to obtain in during the very short timeframe between the beginning of the application and the deadline. Note that there is NO MENTION of it whatsoever in the entrance requirement published on their website:

I hope you guys from abroad sent in a equivalence statement when applying, otherwise you're done.
Ironic that a country which capital is also the capital of the EU doesn't give a damn at all about the Bologna process and ECTS credits...
