Hi sunny, its not any big problem as u think. Just u have fear of failing in exam in front of others. Many will going to fail in exams for different reasons so don’t think that only u may going to fail. First of all leave that fear because only a book knowledge will not going to decide ur future. Even if u failed in exam don’t worry u have next chance for doing it more better than before. So be confident and bold and also we are boys we should not worry about all this things. Its ur life u should live it happily don’t be worried about others and i think ur parents will also understands ur situation and support u. As amit said many are happy even if they failed many times because they know a single sheet of paper cannot judge their mind. So be a bold Man and face whatever may come in ur life.
