Hey vanya! 

Your 12 th percentage is good but your DUJAT percentile is not good enough to fetch you a seat in any of the collefes of DU for BMS. As , with this percentile , i can expect your rank to be more than 1k but for getting a seat in BMS in college of DU , your rank must be under 700. 

To check the previous year DU JAT cutoffs , follow the given link:

Hope it helps!
