I m first year mbbs student who believes that concept must be crystal clear besides knowing and just menorising facts in order to conquer the competition world... I can teach science from class 6 to 10... Biology eleven and twelve class... And first year mbbs students... The subjects which I chossed was just becoz knowing facts in science is not enough... U must be able to imagine all what u study and apply it in ur daily life... I promise u that we would achieve this goal... + more - less
