JEE Main 2020 (2nd, 3rd, 4th, 5th, 6th September): Memory Based Questions, Topics, Concepts & More

JEE Main 2020 (September 6, 5, 4, 3 & 2): The National Testing Agency (NTA) is conducting JEE Main 2020 today. It has already conducted the JEE Main 2020 on 1st, 2nd, 3rd & 4th September with all safety due to COVID-19 pandemic. Most of the students were satisfied with the arrangements in the examination centres. We have talked to some students and asked them to recall some questions & concepts on which questions were asked in the computer-based online test of JEE Main 2020 today. Most of the students were unable to recall the complete questions however they told us about important concepts from which questions were asked.
