Dear student,
                          You must choose your subjects as per your interest. It is very important that you go for what u want to study otherwise you will regret it later.
As per your percentage you can opt for commerce stream along with maths or hindi. If you are interested you can go for humanities as well. It is a very interesting stream.
If you want you can go science stream as well if you are really interested in it.
You must  first decide what you are aiming after your 12th for your graduation.
Lastly i would suggest you to go for the subjects you want to study. All the streams require equal dedication.
All the best!
I hope this answer was helpful for you.
