Find out how wide your choice of options will really be. Many universities appear to offer a wide range of options, but sometimes they are clustered into specific streams. This can drastically reduce your actual choice. Subject to some timetable constraints and guidance by the Senior Tutor, you will have a free choice at Imperial College. Ask about the teaching.
Lectures are central to university teaching.
At Imperial College, we augment the lectures in physics and mathematics with Classworks, Tutorials, and Office Hours. Classworks are problem solving sessions, designed to illustrate topics first raised in the lectures. Instead of a single lecturer, a Classwork session typically has about ten demonstrators to give you individual help with the problem sheets. Tutorials give you the opportunity of finding out more about physics and sorting out any problems you may have. Be sure to ask about the actual size of the tutorial group, and how frequently they are held.
