When I joined KCL now a few years ago, the prospect of studying in the city of London, in what is one of the biggest universities, seemed daunting. However, with now a bit more perspective and stories to share it has been and continues to be enthralling, exciting and thoroughly enjoyable in all its facets.
All courses have lots of content, from a wide range of subjects, and the university gives lots of freedom to their students to tailor their career as they so please, with the possibility of taking modules out of their own faculty and departments. Lecturers are experts in their field and tend to be very international. Seminars are more of a gamble and it all depends not only on your group and if its active, interested, participates, but also on who is leading said seminar and how they take that job on. The libraries are often crowded and sometimes all the core books you need are taken out, but there is a lot of alternative spaces. All libraries are 24/7.
Regarding, student life, the student union is brilliant, with groups and societies from all interests. They hold weekly events, socials and get-togethers that ensure you can socialise all while discovering new passions and fulfilling older ones. On top of that, the university is in wonderful London….. which just about says it all.
