You can definitely get a seat in one of the 15 colleges accepting DU JAT scores. You can check out these for BMS 

• Keshav Mahavidyalaya 
• Ramanujan college 
• Ram Lal Anand college 
• Shaheed Sukhdev college business studies 
• Sri Guru Gobind Singh college of Commerce 

You should wait until you get the best choice you can get with your rank as many seats go vacant. 

Good luck
