hi,

see ssc cgl is a combined graduate level exam, so the minimum qualification is you need to have graduate degree in any discipline, it is a 4 tier system exam where tier 1 and tier 2 are computer based exam, where tier 3 and 4 is descriptive paper and computer proficiency test.

see if you have completed your bsc course and have certified you can surely apply. however  candidates appearing in the final year of their graduation can also apply, however they must possess the  Essential qualification on or before 01-01-2020.
