Hi i am just wondering if it is waste of a choice to apply 2 same programs in a same faculty?
Such as Mechical engineering and Chemical engneering? say if i am rejected by mechanical then i will probably be rejected by chemical too?
No way to know for sure. You might get both offers, or just one, or neither. With a combination like that I'd say it's fairly likely that if you were rejected from one it would be because your personal statement made it clear that your real interest is the other course.
