Hello,

In terms of order of Difficulty – Maths was toughest while Chemistry was easiest amongst the three subjects. This paper was overall of Moderate level as per students.

Mathematics – Moderately to Difficult. Weightage was given to chapters of Calculus, 3D & Vector Algebra. There were some good and tricky questions from Binomial Theorem, Permutation & Combination, Probability & Matrices, Properties of Definite Integral & Differential Equation. Few tricky questions were also asked in chapters of Circle & Ellipse. Questions were of moderate level and lengthy.

Physics – Easy to Moderate. This section was balanced with questions covering almost all chapters. Some good questions were asked from Kinematics, EM Waves, Electromagnetic Induction, Heat & Thermodynamics, Semiconductors, Modern Physics & Optics. Some Numerical Based questions had lengthy calculations but were easy.

Chemistry – Easy. Organic Chemistry & Inorganic Chemistry had more weightage. Physical Chemistry was asked only in Numerical Based Type. Questions were asked from chapters of General Organic Chemistry, Oxygen Containing Compounds in Organic Chemistry. In Inorganic Chemistry questions were asked from s-block & p- block elements, Ores & Metallurgy, Environmental Chemistry. Questions directly from NCERT were asked. Overall, this section was easy.

Thank you
