Study Abroad is an awesome experience!

The best way to make the most of a study abroad is to get out of your comfort zone and be proactive in making friends, sightseeing, and travelling. I made some of the best friends from all over the world while on my exchange, and they're what really made my experience unforgettable.
In terms of academics, I found it to be much easier than classes at home. Fewer assessments, more breaks throughout the semester, a lot of online lectures... I recommend taking electives (if possible) that you're interested in to keep academic stress to a minimum.
Accommodation (on-campus housing) was standard. Felt safe going to and from class, flat was equipped with all the essentials, but my flat in particular had many maintenance issues that took a while to be dealt with.
