BBA

Hi,
You should never do BBA from a polytechnic college.

BBA means Bachelor of business administration. For pursuing BBA, you have to score good in class 12th. You can take any stream for BBA among finance, sales and marketing, HR, production, disaster management, etc.
After completing your BBA, you can go for MBA, if you want. You can also take a job. There are so many recognized universities, which offer placement opportunities, so you can take this chance.
Best of luck.

Best University in Delhi for persuing BBA are:-
Delhi University
Guru Gobind Singh Indraprastha University
Jamia Milia Islamia
Best of Luck.

You should not think about CA, if you have done BBA. It is better to pursue MBA after completion your BBA.
Why you want to waste your time in such a difficult course, while you have an opportunity to take an easier task i.e. MBA.

You should opt for B.Com.

It is not possible to get admission at this point of time. You may try next year.

You can opt for Canada or Australia. Both countries are super affordable with lots of job opportunities with easy visa policies. US market is on a little low right now and they are finding new ways to send people back to their respective countries without a job in US. Canada and Australia do not have such issues. Besides, part time job options while you are studying are great.

Hi,
Yes, you can get a job but chances are less. Further studies are suggested for you.

Mathematics is not required for BBA program.
