Yes, it is the one of the branch in M.Com.

You can apply for CDS or NDA.

Sorry, but how can you do B.Sc with commerce in class 12th? You should either practice for CA or you can do B.Com and after that MBA.

B.Com would be a better option and you can do MBA from a top B-School and business maths is not mandatory for B.Com but you will not be able to do B.Com (Honors).

No, you are not eligible. Instead, you can opt for B.Sc computer or IT, then go for M.Sc and M.Tech.
All the best.

You can opt teaching as a career or can go in the banking sector also.

Hi Tuhin,
Tuition fee may range from Rs. 12 to 40 lakhs a year. Here is a country wise break up if it helps. Please note that tuition fee is subject to change and differs with universities. This is just a rough estimate.
USA - Rs. 15 to 40 lakhs a year
Germany - Rs. 0 to 15 lakhs a year, German universities are almost free or charges minimal amount.
SIngapore - Rs. 12 to 20 lakhs a year
Australia - Rs. 15 - 20 lakhs a year
You must also consider an additional expense of Rs. 5 to 10 lakhs a year for living expenses.
I hope it helped.

N.C.E.R.T is the best books for 10th. All the basic concepts are very well explained in that. If you want to refer some more books than for Maths-R.D.Sharma, Science-Arihant.
