Hello Zenith,

Sorry to hear that..As you cannot pass the exam you have to reappear again. And even the students appeared for the exam are even allowed to apply for the rechecking or re-evaluation of the answer script in case the students are satisfied by the marks awarded to them.
You can appear in 3 subsequent exams to clear all the subject in which you didn't pass .So study in a focused manner and don't give up.
