Currently a student in Unisim PT too. To complete the course in 3 years, you need to take up the maximum credit units per sem (20 credit units which is about 4 modules per sem).

Honestly, it is quite taxing especially when you have projects and exam coming up while trying to handle your daily work.

The good thing is that the classes are not compulsory so if you are smart enough, just skip all the classes and study on your own.
