Hello Aspirant,

Unfortunately there is no option to change your stream in class 12th because registration in the board for class 12th subjects has already been done in your class 11th and now you cannot change your stream even if you change the board then also you will have to read class 11th again. So now you have only two options either you repeat your class 11th from another board or continue with commerce stream in class 12th as well.

For more details regarding this you should ask to your school authorities, they can give you much detailed information for this.

I hope this information helps you.

Good Luck!!
