Course isn't showing up

Hi, im going to Northumbria to do Biology C100, however when im updating my finance these are the only courses that show up:
(BSc Hons) APPLIED BIOLOGY 3YR C100 3 years Bachelor Degree with Honours
(BSc Hons) BIOLOGY SW C100 4 years Bachelor Degree with Honours Includes placement year(BSc Hons) APPLIED BIOLOGY SW C100 4 years Bachelor Degree with Honours Includes placement year. I will be only doing 3 years as far as I know and will not be doing a placement year. Should I still register under the 4 year course or the applied biology that is 3 years but has a different course name
