Hello aspirant,

YEs, you can make corrections in the CUCET Application form and could change your subject exam code as well as qualification details.,  but that can only be done when the correction window for the application form will be out. If candidates commit any mistakes in the application form, they can correct it from the applicant login window . Corrections facility can be done after the end of application process. Corrections can be done via online mode only.

Further, to know more about the CUET correction facility, you can follow the below mentioned link to know more : https://university.careers360.com/articles/cuet-application-form-correction

I hope that this will help.
