Science is an essential part of everyday life, so is of any competitive examination. In WBCS examination it is a mandatory part from which questions are asked. But area of science is vast, so I have decided to present science in a lucid manner so that every examinee can do his part and can get enough marks to clear this examination. This will definitely benefit you. Thank you for watching this video.
