Hello aspirant

Hope you are doing great there. No this will not create any problem by the cbse side but yes you might have to face difficulty in terms of time which will be wasted during traveling. You can take the dummy in class 12 . Some schools offer but the cost for that is quite high. They almost charge a double amount for admission in class 12 then that you have paid in class 11th.

I hope my answer helps

Wish you all the very best!
