So far it’s been a few months I’ve been studying at UG, and my experience has been mixed. If you’re international looking to come here you have to understand that majority of the students are from France, so yes, learn how to speak or better still learn French. That being said you’d still find non natives like yourselves, but the chances you’d be friends with them is low. It was easy during covid cause you could just be home and attend classes but now that it’s in person. Learn up on your French.
