The paper 1 of JEE Main 2019 is being conducted from April 8 to 12 (except April 11) at 470 centres across the country (including 9 outside India). The National Testing Agency has successfully concluded six slots of JEE Main 2019 Paper 1 on April 8, 9 and 10. A total of 935741 candidates have registered for paper 1 of JEE Main 2019 as per NTA statistics. Various teams from Jagranjosh.com have collected feedback of students about the difficulty level of Physics, Chemistry and Mathematics sections of JEE Main Question Paper 2019 from different JEE Main Exam Centres. Appeared students have also shared memory based topics and questions with our team. Here, we are providing all the memory based topics and questions shared by students who appeared for the exam on April 10, 9 & 8. We will also share memory based questions of Day 4 (April 12, Shift 1) once the exam got over.
Students who appeared for JEE Main 2019, are confused about their chances of being shortlisted for JEE Advanced as they have no idea of the cut-off to be released by NTA. Experts at Jagran Josh, after analysing the prominent factors, have prepared the expected cut-off of JEE Main 2019. This expected cut-off is totally based on the general calculations performed for the trends in previous years and number of candidates appeared in JEE Main 2019. Details can be checked from the following link:
