Hello Manjeet. See, after class 10 almost every one is confused about the streams. I would suggest you to do some research on the internet regarding the fields in which you have interest. For instance, if you have interest in numbers, search for the career opportunities you can have in various fields with numbers. (This field of number & statistics is most sort out career nowadays) 

So, look into your interest, talk with your parents, and choose the stream. 

All the best. Fly high.
