I absolutely love UCL, especially thanks to my degree. In Arts and Sciences, we are allowed to pick all of our modules, which is amazing. I enjoy the diversity of people and the multitude of activities and events. I have met so many great people and there is not a single day where I would say I am bored.
The only problem I could notice is the low amount of classes, which is sometimes too low for me. Weeks can be very empty if you do not fill them correctly. Also, many of the seminar tutors are quite bad. These are the only two negative things that I can find about UCL.
