JEE Main 2024 Session 1 ALLEN’s Percentile Predictor is LIVE Now!

The fourth day of JEE Main-January 2024 Session 1, which is country’s biggest engineering entrance examination for admission to BE-B.Tech course, was held on Wednesday.

The examination was conducted on computer-based mode. Dr. Brajesh Maheshwari, Director of ALLEN Career Institute Private Limited, said that based on the feedback of students and the feedback received on ALLEN Digital, the paper was based on NCERT syllabus. In both the shifts, Physics and Chemistry paper was easy while Maths paper was calculative.

Physics

According to the feedback received from the students, the paper was easy in the morning shift. Questions were asked from almost all chapters of class 11th and 12th syllabus. From Mechanics in class 11, one question each came from U&D, NLM, Kinematics 1d and 2d, Circular COM, Rotation Elasticity, Thermo, Fluid, Sound, SHM, Gravitation and Errors. One question each was asked from Geometrical Optics and Electrostatics from the chapters of class 12. Similarly, two questions came from electricity in which one question was based on Equivalent R and a question came on dielectric in capacitance. One question came from MEC, one from EMI. Whereas two to three questions were asked from Modern Physics, a question based on logic gate in Semiconductor was also asked.
