Hello dear,

CUET 2022 guidelines state that candidates may select up to six subjects from the 27 domain subjects available for the test.

The CUET Exam is divided into four portions: two language sections, one domain section, and one overall section. The candidate chooses the number of subjects; it could be one or six. Students must, nonetheless, choose at least one language from the 1A category, which consists of Tamil, Telugu, Kannada, Malayalam, Marathi, Gujarati, Odiya, Bengali, Assamese, Punjabi, Hindi, Urdu, and English. The second category, 1B, is optional and not required. It is preferable to stick with the language a student chose in their most recent class (XIIth).

So, it's completely fine if you have filled a slot.

thank you
