It was a paper of 180 marks, said Ajay Kumar Sharma, National Academic Director (Engineering), Aakash Educational Services Limited.

“Student further opined that the topic coverage was full in physics, more or less complete in chemistry, whereas, there were very few questions from Calculus. probability (4) matrices and determinants (4) were notable mentions. Overall, it was an easy to moderate paper with math>chemistry>physics as the subject-wise difficulty level,” he added.

Chemistry was a balanced section with questions covering chapters of classes 11 and 12  equally. In inorganic chemistry questions, were directly from NCERT. In physical chemistry, questions covered chapters of titration, electrochemistry, thermodynamics (kinetic theory gases). In organic chemistry, questions were mostly asked from amines, biomolecules, and oxygen-containing compounds.

Physics has questions mostly from class 11. Some tough questions were asked from chapters of current electricity, optics, rotation & modern physics. Overall, the section was easier compared to the other two subjects as per students.

There were questions from functions, continuity & differentiability, application of derivatives, definite integrals. Some good questions were asked from chapters of probability, complex numbers, and 3D geometry. Some Tricky questions were asked from circle & parabola in coordinate geometry. A tricky question from trigonometry was also asked. Students felt this section was the toughest with more weightage given to class 11 chapters,” said Ramesh Batlish, Head, FIITJEE Noida.
