Hii,

Unfortunately, CUET doesn’t offer corrections after submission, especially for subject selection. Missing Physics even though you had it in Class 12 means you may not be eligible for related courses that strictly require it like B.Sc Physics, Engineering, B.Sc Genetics, etc. However, you can choose courses where Physics isn't mandatory,check if the university allows submitting an additional subject.

Some universities may interpret your application flexibly, so reach out to their admissions offices promptly.

Hope you will find it helpful!
