Learning activities and methodology
Synchronous lecture sessions (3 credits) (PO: a, CGB1) During these sessions we will cover the course topics with the aim of using theory to solve problems. Practicals, working individually and in groups (3 credits) (PO: a, CGB1) During these sessions we will solve exercises of different levels of difficulty.
