Documentation About

jutge-org on GitHub

I am the coordinator or co-coordinator of four courses taught at FIB. All the problem sets are on Jutge, the exams are held on Jutge, and the laboratory sessions are based on Jutge. It's clear, isn't it? Right now, I don't know what I'd do without Jutge.org.
