Thank you so much everyone for your kind replies. And I'm not afraid to fail the exams as I'm pretty aware of the kind if exams and the preparation required. Despite the fact, people fail the exams even after preparing for an year, or if they pass, many fail the interview part. I'm appearing in exams for the sake of exams only. And I'll try my best to prepare as much as possible before the exams.

Thanks again everyone!
