JEE Main Analysis 2019: JEE Main Paper 1 for the January session was conducted from 9th January 2019 to 12th January 2019. With 2 shifts every day, there were a total of 8 shifts spanning across 4 days. Earlier, we published the JEE Main analysis 2019 of individual papers. This JEE Main analysis 2019, however, was based on the memory-based questions shared by students from all across the country.
After the release of the JEE Main question papers by NTA, Experts at Embibe have analyzed the papers in details. Embibe has a knowledge graph of more than 15000 concepts just for JEE Main! Because of the knowledge graph, we can analyze exams at the concept level and prepare students on what to expect in exams and how the current exams have fared.
So, in this article, we will provide you with the most comprehensive JEE Main Analysis 2019 for the January session. Read on and get a better idea about what to expect in the April session of JEE Main 2019.
JEE Main Analysis 2019
Apart from the Knowledge Graph, Embibe has a large amount of student attempt data. This data collected on our platform over many years along with Embibe’s Knowledge Graph gives us insights into the paper on various dimensions – difficulty, time to solve, important concepts and chapters, and concepts and chapters where students are likely to make mistakes, etc.
JEE Main Analysis 2019: Were There Concepts That Were Asked For First Time?
Though JEE Main Syllabus has over 15000 concepts, only 30% of concepts are typically covered in the exam. So, were there new concepts that were never asked in the exam before? Let’s examine.
| Paper | New Concepts | % New Concepts |
| 2019 JEE Main Online – 09 Slot 1 | 47 | 2.69% |
| 2019 JEE Main Online – 09 Slot 2 | 40 | 2.29% |
