Best experience would be the lecturers. Very knowledgeable and approachable, answering any and all questions. Worst experience would be the students union and their apparent lack of administrative support.

Nothing to add

Choose your favourite subject and place to learn and live. Don't let it all up until the last minute and it will be hard for you to succeed. The exams are not that hard as well so don't worry about anything. A lot of self-research is required at this level but it is interesting and exciting.
