In the UK, courses are called "modules". Modules can be available for the semester or the full academic year. Classes are taught mixing lectures, seminars, tutorials, labs and fieldwork for a full learning experience. Similar to that of the University of Illinois, class sizes will vary at this large institution. Large lectures are accompanied by smaller discussions, which range from 15-30 students per classroom.

Note for Business students: Please list the University of Manchester Alliance Business School. The general University of Manchester program does offer business courses as shown at the course catalog link above, but more business courses will be available to you if you are admitted specifically to the business school.
