BBA

Both of these options are dynamic with good career prospects, all that matters is how well do you perform in the academics and how well do you maintain your CV.
If arts subjects are fine for you, and if you wanna take the judicial or civil exams, then BA is preferable. And in case maths, accounts and finance and management is your cup of tea, BBA. is fine.
Good luck!

At starting you may feel it's tough but BBA it's a more interesting subject and involve accounting subject. Subjects will differ form university. Science students can pursue BBA easily.

No! Both will suck your money and you will land nowhere for placement. If you really want to do BBA then I'd suggest you to go for Saheed Sukhdev College from DU or IPU. See, it is very much necessary to do MBA after BBA because as you know that salary of a BBA graduate is nothing but 18k or 20k. But if you have MBA too then your salary will definitely shoot up. I am suggesting you to go for a Govt. college for BBA (or if you want a private then please choose any low-cost college as it saves your money a lot for MBA). Along with this, prepare keenly for CAT/MAT or IIFT. I know you are brilliant. Feel free to ask anything.
Best of luck!

Not all colleges have criteria of 50%.
But these colleges won't give you a good placement either.
You can try colleges like St.Hopkins in Bangalore.

Basically, BBA stands for Bachelors in Business Administration and BCA stands for Bachelors in Computer Applications. So there is a vast difference between both of them and they are different fields altogether.

You can always check on the internet for available coaching and examination centers for GMAT examination. But you must not forget to maintain consistency in your academic performance in BBA for getting a good college.
