hi,

see you did not mention which course you are pursuing, however atkt i.e Allowed to keep terms (ATKT) is a process in the Indian education system to allow for those students of pre-graduation and graduation to study in the next grade if they have backlog  in 1 to 4 subjects, now see there is no need to become disappointed , but you must clear the supplementary exam in order to get successfully the pass certificate, see graduation is important to get a decent paying job, also you must complete it since you have invested your 3 years of time for it. after completing the graduation you have to think whether you want to go for higher study or job, do comment in the answer if you have any other query.
