Is there a 2.5% deduction in marks???

Ok so i want to take psychology hons. but I don't have psychology in 12th as my subject. I read on some forums that there is a 2.5% deduction in your final score if you apply for a course that was not in your subjects in cuet?? Idk how true that is also rhe forums were for like 4-5 years ago so idk if they are trustable either. Can anyone please confirm this?
