Computer Science course. The course had 32 subjects spread throughout 6 semesters (3 years). I started the course after finishing the higher education course. In the end the total number of ECTS was 185. Since I finished the previous course, some of the subjects were automatically credited (I did not have to redo the subjects). This also meant I had more free time, and so, I decided to do some subjects earlier.
