if i fail in additional subject of class 12 th CBSE will i consider as pass
No, as per CBSE rules, students who fail in any one subject, will be considered to fail in Class 12. So, if you fail in any one subject, you might have to re-appear for the test.
Hello Sourabh
NO, if you fail in any additional subjects in your class 12th examinations, then you will be considered as fail in your class 12th exams. According to CBSE rules, if a students fails in more than one subject then he will be declared failed.
Further, in case of CBSE examination one needs to pass exam of each subject irrespective of whether it is additional or not to pass the board exams. In case of failing the additional subject exam he/she has to re-give the exam at appropriate time after registering for it as dictated by CBSE .
I hope that this will help.
