CBSE 12th

You can learn English by reading English newspaper, articles and watching English movies most easy way of all try improving your vocabulary try learning new words and then just learn how to put them together to make a fine sentence, it will take time but you'll learn it.
All the best.

The eligibility for a course basically depends upon the eligibility criteria of the institute/university that you are applying for, majorly you have to opt for physics in class 12th if you are in the science stream as it is mandatory in most of the schools.
Hope this helps.

You can opt for B.Sc (agriculture).

I suggest you to choose BBA [Bachelors in business administration]. By pursuing this, you will get better opportunities and good career option. There is a myth that there is no value for BBA and MBA, but that is wrong. so according to me BBA is good.

CA is best choice in commerce, you can also go for:
B.Sc economics
B.Com
BA
D. Ed.

Please mention your class 12th branch.

What was your branch in class12th?

Hello Ananya,
Yes, of course you are eligible for foreign language applicability, only qualification required for applying is just to clear out Class 12th.

Sorry, but don't think you will get a government college, but you can try some other university examination.

B.Com, BBA, BBM all have good future. Almost all companies require students from these background.
