Hey Nandish,

You should continue to study in CBSE .

Because the marks you will get in 12th board will be high than if you compare to any state level exam. This may be benifite for you.

If you want to do engineering in future then i will recommend you to study in CBSE. The quality of eductaion in CBSE and level of question is very good.

CBSE will continue increase your potential and it is necessary. Also your english will be more improved.

You will not face any problem in future because you are from CBSE and you know then level of CBSE very well.

Good Luck!
