I've been putting this off for years, for the same reason. I have a degree in Math and Spanish, and I'm afraid my math degree wasn't rigorous enough to be recognized as one in Spain (although with many all nighter homework and study seesions, it definitely seemed rigorous enough here!) Do you know any other benefits of getting it homologado a grado except for it allowing you to enroll in colleges there without entrance exams, etc.? For example, would a school be able to hire you if you only have it homologado a grado? (that is, a private school.) A school I interviewed at said they couldn't hire me without having my degrees homologados, and to call them when I got them homologado. But like you said, the full recognition I'm guessing could take years, and since I'm 6 years out of school, there's no way I'm going to take any missing math courses!
or do you know, if you get the grado, can you apply later to get it fully recognized? or is it like that catch-22, if you apply to get a convalidacion de estudios, you can't later apply to get your titulo homologado?
thanks for any info!
