Dear student,

Yes you are eligible. Even the final year candidates are eligible.
CAT(common aptitude test) is the Entrance examination conducted by IIM.It is held in the month of October and November.
Eligibility criterion for CAT:
The candidate must hold a Bachelors Degree, with at least 50% marks or equivalent CGPA [45% in case of the candidates belonging to Scheduled Caste (SC), Scheduled Tribe (ST) and Differently Abled (DA)categories]
Candidates appearing for the final year of bachelors degree/equivalent qualification examination and those who have completed degree requirements and are awaiting results can also apply. IIMs may verify eligibility at various stages of the selection process.

All the best.
