Hello aspirant

This is a big mistake , how can you select a wrong board.  Anyways as correction window is closed , nothing  can be done now .

First thing don't be panic , think calmly , send a mail to official website of cuet .

If they are responding it is well and good . You won't face difficulty at the time of entrance exam but at the time of counseling this issue can create a great problem.

If you are not getting response to your mail , you woll have to go to venue of cuet . Any how you will have to solve this issue otherwise your one year time will get wasted.
