Is it fine to give two years after graduation for clearing MBA entrance exams as i was unable to clear CAT and CET this year, plz help

no its not a wise decision. If you think you clear CAT or XAT this year then you wait. otherwise checkout a good college and take admission. gap in education is a major problem during placement in good companies.

if u can sacrifice everything and are ready to clear cat xat then i would say that go for it as without cat xat or the other prestigeous exam u wont be able to get admission in a good college. and be possitive, no need to depress for this years failure, it happens with many every year and they wait
