Though I am very keen on SSCBS for BMS but how should I now place my prefrence of subject and college. And now because of delay, securing seat is crucial. Please suggest 

With this score what are my chances at SSCBS for BBA-FIA

Chances for BFIA are less as it has some 40 odd seats.. When it comes to preference put sukhdev at top 2 choices..  Choose the one first which you are more eager to persue and at 3,4,5 you can put sggscc ddu and kmv according to your preference. All are equally good but remember if you don't get sukhdev in first list you will be alloted your 3rd preference so choose your third preference wisely out of the above three. 

Thank you so much!
