BBA

Dear
as you are from science background, you can do you bachlor in any science or art stream instead of doing bba or bbm because you want to do MBA too. Take BA economic in you graduation and prepare for CAT as you have science background, definitely you have an edge.
If you got good colleges for BBA than you can do that too but I am suggesting you to do simple BA in economics.

your rank is not good for taking admission in the best college of IPU like maharaja agarsen,VIPS,etc .but all the college of IPU is good. I think u have to allotted kasturi ram college CPJ-CHS ,DIRD .if u have Delhi candidate.

You can go for any good private colleges.Uei global can be one choice as it has good placements and internship options.they also provide earn while you learn optionsas well which are rarely provided by colleges
best of luck

BBA is into Management and Law. BMS is strictly into management and is a mix of BCom and BBM.
Both are good but BBA has more scope and placement opportunity and also good if you want to do Mba further.

Which college Rohaan. I think this question of yours is a part of some earlier question and hence it seems incomplete as a separate question. I suggest you put it up again completely so that Experts can give you a proper and suitable reply.

Dear harsh Jhanjharwal.if you have some reservation you will get out side the IP campus. ok. all the best. otherwise try with management quota all the best.
