Last updated on August 17th, 2021

JEE Advanced 2021 notification has been released by the IIT Kharagpur on their official website. And along with notifications, important dates and syllabus for the exam also have been declared. JEE Advanced exam pattern changes every year, however, JEE Advanced syllabus remains the same. The syllabus for Mathematics, Physics and Chemistry is available separately in the official brochure of IIT Kharagpur. In this article, we will only talk about the chemistry subject only. JEE Advanced exam is an online examination that consists of two papers named Paper-1 and Paper-2, and both are compulsory to attempt.
