JEE Main 2021 B.E./B.Tech Question Paper- July 22, 2021- Afternoon exam was rated to be of moderate difficulty by the experts. Conducted on the second day of the JEE Main 3rd Session, JEE Main July 22, 2021 exam was not preceded by a morning shift; meaning that only one exam was held on July 22 (afternoon session). The Physics section was the most difficult section of the exam, featuring a significantly high number of complex calculation-based questions, especially from Mechanics, Electrodynamics, and Modern Physics units. Mathematics was the second section in terms of the difficulty level, featuring a few tricky questions from the Binomial Theorem and Probability. Chemistry was the easiest of the three, heavily featuring questions from Organic Chemistry (II), and Inorganic Chemistry (II).
