Maropista,
God don't tell me it was a lot quicker! I'll be knocking my head against the wall for days!!
Many of those steps are the same you have to do with the "homologación", and there are some snags with convalidation:
1) If the university doesn't validate enough of your subjects, then you have to start from the very beginning.
2) As I understand it, public universities require that you initiate the process through the ministry of education before they even look at your case. Then, once your case has been looked at a decision is made. If the accept the entire degree, then you're set. If you have to do additional coursework, you have then go back.
3) Also the ministry often requires that the completed coursework be done at a public school or one that is associated (adscrita) to university.
All I'm saying Madridmanjim is that you have to look at your case carefully and make sure you are taking the best route for you.
I can only tell you from my personal experience, but maybe there are quicker ways.
