first of all, these are pieces information regarding the procedure if you are in Romania at the time of application

because you have a quite strong beaurocracy to fight against

as you might have found out while studying in Romania
you have to contact the Spanish Embassy - the Education and Culture Consulate (or so somthing). that's in bucharest, on Mihai Bravu Str., in the building of the Iulia Hasdeu HighSchool, first floor. or maybe there is something similar in Iasi? here, you'll get some papers you'll have to fill in and a list with the necessary documents. among them are a few legalizations (??-if that's the right word in english ??) of "diploma de licenta" and "foaia matricola". for that ones you have to knock at the doors of the
ministery of education (MEC) and that of
foreign affairs (MAE) and the one of
justice (MJ). you'll find it quite difficult, i'm sure. i don't want to frighten you but you'll deffinetly have to have someone with you that speeks romanian. i suppose you don't as long as you wrote this request in english.
after you "gained" all this legalized copies (that might take about 2 months - the most time consuming is MEC) you have transfer 80 euro in an bank account that is specified on the sheet of paper that those from the embassy gave you.
with the receipt for this payment (a copy, of course) and the filled in forms from the embassy.... and the legalized copies....you bild up a file that you'll send by mail somewhere in spain.
the down side of this exam-free route is that it takes about 8 to 12 moths
since they receive your file in spain!! so....you do the math. but there are people that made it. and it works. slow and steady
so .... GOOD LUCK!!
