Does FT in one subject CBSE Class XII mean the student has to reappear?

No, FT in a CBSE Class XII subject does *not* automatically mean a student has to reappear for the entire exam. FT stands for "Fail," but it signifies a failure to meet the minimum passing grade in that *specific* subject. The student will only have to reappear for that *one* subject. They will pass the overall exam if they pass in all other subjects.
