See let me remind you, CBSE works on its specific guidelines on making paper for the students. According to me every paper is average so that all students can pass their examination. For preparing compartment examination, collect last seven year compartment papers of All India, Delhi and Foreign and then solve it accordingly. Lot of questions are asked from the previous year compartment papers by CBSE. There is no myth that the papers are hard or easy, a student predicts the paper according to their knowledge and study. So don't worry about them, if you'll work hard you'll definitely achieve your dreams so don't worry and work hard. Solve derivations, remember the concept always, as most of the questions asked will be concept based. No need to worry. Best of Luck!
