## JEE Main Exam 2023 Analysis: Mathematics moderate, Physics, Chemistry easy

JEE (Main) 2023 Paper-I exam for Day 2 concluded at 6 pm on January 25, 2023. The students who appeared for the examination had to report to the exam center at 1.30 pm and the exam started at 3 pm. Paper I difficulty level was moderate for Mathematics and easy for Physics, Chemistry.

Students were not allowed to carry anything inside examination hall except a transparent ball point pen, Admit Card & Aadhar Card. All guidelines as released by NTA earlier were followed for the safety of the exam takers. Every student was made to go through a sanitizing station where they had to sanitize themselves through a foot press lever.

**JEE Main Exam 2023: Paper Pattern**

There were total 90* questions and Total marks of JEE Main Paper-1 was 300. The paper had three parts & each part had two sections:

Part-I- Physics had total 30*questions – Sec-I had 20 Multiple choice questions with Single correct answers & Sec-II had 10 Numerical based questions out of which only 5 had to be attempted.
