I think if any one has grip over any subject he can get good marks in that subject. On the other hand subjects related to our fields are not there( i mean subjects related to particular fields such as Electronics,Electrical, Telecom etc ) and we can get Physics or Mathamatics as optional subject, which are some how related to our field but I think these subjects require lot of hard work as well as mind work, so should we choose these subjects? Or other comparatively easy subjects? Though we can get solid marks in these subjects(Physics or mathamatics) if we get command on these subjects.
