Recognizing studies

Finally I received the academic transcript of second semester from Spain. Now my faculty has to recognize my studies which I did in Spain and it will take about one month. There are some ambiguities how many ECTS my studies are worth in Finland. University of Alcalá have not replied for my inquiries about the credits. I assumed that the credits I earned are ECTS but my faculty did not accept them right away as ECTS. One Spanish credit means ten hours of lessons and one ECTS credit means about 37 hour of work. Therefore these credit systems are not very comparable.
