In Physics, there were more questions from Class XI. Questions from Biomolecule and F-Block in Chemistry were seen for the first time in September, JEE-Main.
In organic, there were Chiral center numerical based on separation technique related and product formed after reaction order. In Physical Chemistry, there was more weightage of Electrochemistry and Surface Chemistry. Under Inorganic Chemistry, questions were asked on Isomeric, VBT, P-Block, and Chemical Bonding.
In Physics, questions from Dimension Analysis and Compound Microscope were difficult. Questions were even asked from Semiconductor and Magnetic Dipole.
