Ive passed class 11th commerce CBSE but now I want a science stream, can I change my stream in 12th class by changing board or anything? I dont want to repeat class 11th.

lubhan cherwoo 21st Feb, 2020
The only possible way you can make the transition is if you change your board ie you can shift from CBSE to State Board,but I do not recommend such a change as to study science you need to have a strong background of which class 11 science is a base to class 12 either you have to work very hard or you shouldn't take the risk ,if you do take the change make sure to work on that with full mind.

The other thing that you can do is further you career in commerce and make the variation to courses like Bcom,BBA LLB,BBA/BMS,BCA(IT and Software), diploma,etc

You can also opt for a course primary diploma outside India in some other field of interest.
