The curriculum, the opportunity to pursue diverse interests in the first two years, incredible facilities (hospitals, lecture halls, libraries, lectures online etc.) living conditions are solid.
What impressed you negatively?
Some people were a little bit cocky but not nearly as bad as one would suspect. A very positive all round experience.
What did you wish you had known ahead of time?
I knew there would be free time but just want to re-iterate. You have lots of free time but there are plenty of things to do on your own. They provide a nice manual at the begining of the day explaining what's available.
