Permissible combinations

Students studying for NST Part II BBS must be able to attend all lectures in both their Major and Minor Subjects. For this reason, only Subjects which do not have any timetable overlap are considered compatible. The recording of lectures is not considered an acceptable alternative to attendance. To help students pick permissible combinations of Subjects, the Faculty Office prepares each year a comprehensive table of incompatible subjects. The most up-to-date information can be found on the Permissible Subject Combinations page.

Home department for BBS students

The department in which BBS students are taking their Major Subject is designated as their "home" department. BBS students should be given access to the same resources and support, such as soft skills training, journal clubs, seminars and facilities, as single subject NST Part II students in that department.

Moving into/out off the BBS course

Please note it is essential for students to contact the Faculty of Biology office when moving out of or into the BBS course, as well as the relevant course organisers.
