Grace marks should be provided for physics because ..   the derivations come in a great amount but only few came... And the students like me who are weak in physics can get marks through derivation and we tried our  best by practicing the derivations thoroughly to fetch marks but very few derivations came and moreover it was tricky and lengthy... So it kind of becomes difficult for students like us because we also try to get good marks in physics and if we obtain bad marks in physics then the whole marking decreases.... This may stop us from going to good colleges...even after studying physics so hard
