Endued is spelled endowed.
There are other problems with this sentence:

As students, we are endowed with many [what are leniencies???] which are taken for granted in the [real world]. What do you mean by "the real world"? Students don't live in the real world?? Please reconsider your wording.
i'm trying to say that while we are in school we are given a lot more opportunities to make up missed work, have extended deadlines, etc. Teachers are much more lenient with us then boss' of companies are. by "the real world" i mean life outside of the school environment.
