Commerce

Hello Tushar,

Go to this link and apply for BCA.
All the best.

If you are good at mathematics, especially probability and statistics, then you don't need to be worried. In the real world, you need three things to be a data scientist- (Which would depend on the projects you take on).
Learn this if you haven't, you will need this more than the other two if aren't familiar with anything in the field.
3. Coding-Since you are a student of commerce, I am assuming that you don't know coding. I suggest you start learning, and in a few months you will know enough to call yourself a coder! Coding is extremely fun, but also requires patience while solving/debugging tough problems.

You are interested in doing psychology studies then I would like to suggest you that after 12th used to take admission in BA with specialisation psychology and if you want to take admission for Mass Media then you have the option of Diploma in mass media which is 3 years certified course.

Eco, commerce and accounts are the main subjects available.

Courses available for you are BCom, BBA, and B.A. in different courses and much more. Go for the link and you will get the know more about the career in commerce:

Any of MNC companies are not going to offer you a job on your 12th basis. For that, you need to complete your Bachelors degree in any stream with a good college background. You are going to apply for companies and if you have been selected in any of the MNCs, then you can take a job in them. Mostly, MNCs prefer Masters degree.

The admission process is based on their own merit list. If you have been selected in merit list then you can take admission for SK Somaiya.

If you want to do B.Sc. When you need to take admission for 11th and 12th Science, then only you can take admission for B.Sc. in IT or computer science, but if you are not a Science student, then you can take admission for BCA. Also through BC, you can also study IT and Computer Science.

Hey,
Since you are interested in doing computer studies, after 12th, you should do BCA and after completing your BCA, you can do MCA.
