The course consists of 3 lectures per week plus a bi-weekly workshop/surgery. Electronic lecture notes and self-study packs will be provided for parts of the course.

Learning activities include attending lectures, problems classes, laboratory demonstrations, and exam preparation.

Summative

This is how we’ll formally assess what you have learned in this module.

Referral

This is how we’ll assess you if you don’t meet the criteria to pass this module.

Repeat

An internal repeat is where you take all of your modules again, including any you passed. An external repeat is where you only re-take the modules you failed.
