JEE Main 2024 April 9 Question Paper with Answer Key: The last day for JEE Main 2024 Session 2 B.Tech Paper 1 is being conducted today, April 9, 2024. The paper is underway in two shifts. Shift 1 began at 9 AM and concluded at 12 PM while Shift 2 will be from 3 PM to 6 PM. Shortly after the conclusion of each shift, its memory-based questions along with their answers will be provided here for all three subjects. Additionally, JEE Main 2024 April 9 question paper with answer key solutions released by several coaching institutes will also be provided here for direct download in PDF format.
The morning shift paper today was rated as 'Easy to Moderate' as per the preliminary reviews of the paper. In Chemistry, theoretical questions were more. In Physics, some questions were found to be lengthy today. Mathematics was the same as that of the earlier days, moderate to tough and lengthy.
