Well, I don't have a screenshot of the above example.sry man i dont understand this can you send a me a screen shot of what your doing?
But electives are units that you are able to choose. A major is when you specialise in a certain subject area in your electives; 8 units from the same subject equals a major. Lets say that throughout your BBC degree, you did 8 units that related to psychology, that means that you have a BBC majoring in psychology.
EDIT: no worries
