Dear Aaditay,
Final merit list be prepared on the basis of Entrance Test: 50% + Qualifying Examination (+2): 50% + other admissible weightage. Whether you will get a seat or not will depend on the relative performance of other candidates who have applied for this. I came across few more queries of this nature (Similar Queries). Going by them your performance in Test falls in average or above average category but you haven't performed relatively well in 12th. There are 360 seats (BALLB 240 +120 BCom LLB) whether you will get one or not, alot will depend on your position in final merit list. I hope it helps!
