Are exams are burden to you ? what you feel abount that days?

They are stressful, but as far as schools are concerned, it is just the most efficient way of testing your knowledge. It is much easier for them to give a single test to 100 people and have a few people with answers to the questions mark them over a few days than to quiz individuals. If you have studied and learned your subject well during the year, you should have no problem with passing as exam :) I actually like exams, as weird as that sounds, my brain seems to respond really well to the pressure of the time ticking away.
