Dear Aspirant,

Speaking from personal experience, according to me the difficulty of the mathematics section is moderate compared to both Physics and Chemistry. Difficulty level can be relative but most people believe that its not very difficult for someone who has done enough practice and has command over formulas and its applications. COMEDK exam is not same as BITSAT. Students find BITSAT comparatively more difficult than COMEDK. Though there's one similarity that the questions are quite direct and formula based as compared to other exams like JEE MAINS. One who has prepared well for BOARD exam can definitely crack this exam.

Hope it Helps!

Good Luck
