I would describe EU as an amazing place to meet people from anywhere all around the world. It’s a huge + for that social part.
Regarding classes, it all depends on the teacher. You have some that are extremely picky and others that are way more chill. With the picky ones, almost no students were able to cheat during exams, with the chill ones, it was a contest of who could cheat the best.
The content of the classes is good, if you stay interested, you won’t lose interest.
The professionals you meet through classes & EU events are an amazing opportunity to build your network and potentially get hired or even start a business. Going to a TEDx event as a staff member thanks to EU was great.
My own advice for any future student planning to go there: plan your own everyday life to be able to both study enough and enjoy the life Barcelona offers [If Barcelona is your destination of course]
