A fun little anecdote....
I decided to try to enroll in the UBA last year. It was impossible to really figure out where to start. I managed to get all the documents for this year. I went to the Min. de Educacion. My high school diploma was rejected because it didn't have a sticker seal on it... it didn't come with one. I asked my high school if they could do that. They of course said no. The min. de educacion says I have to get a letter from my high school stating the reasons as to why they can't put a sticker on my diploma, then get it notarized, apostilled, translated, and certified. I'm considering making a sticker seal myself and just putting it on my diploma. My transcript was rejected because the first two pages are switched. If we just change the order, the stamps won't match up correctly so they won't be valid. I was told I'd have to start the process all over again... starting with asking for another official transcript (since this one already has mismatched stamps). UBA is a total joke. I actually already studied at UBA for a semester (through FLACSO), taking direct enrollment classes and actually passed all my classes. And I have a college degree. But my high school transcript doesn't have a sticker and the state of california mis-stapled my transcript. SO I'm apparently unqualified to enter in the UBA. I wouldn't bother with UBA unless you are married to an Argentine who will never leave Argentina and are thus quite literally stuck here forever more and can't afford a private school or no private school has the program you are interested in. The difficulties in enrollment are just foreshadowing for what UBA is like...(it took me 2 weeks to find my first class at UBA... why? because i got to class on time. the third week i sat in the class room for over an hour after class started before a man walked in casually smoking... i asked him about the class... turns out... he was the prof... a hour late... the students strolled in afterwards.... or how about this? an argentine friend of mine completed the cbc before being told that he was not officially enrolled... and thus had to do it all again... he gave up. now he is more successful than any college grad i know).
