JEE Advanced 2021 Question Paper with Solutions: The Definitive Guide for Aspirants

The JEE Advanced 2021 was conducted by IIT Kharagpur on October 3, 2021. It remains one of the most significant papers for aspirants to study because of its unique question types—such as the introduction of "Question Stems"—and its balanced but challenging distribution of topics. Unlike JEE Main, the Advanced exam is divided into two compulsory papers (Paper 1 and Paper 2), both featuring a mix of Multiple Choice Questions (MCQs), Numerical Answer Types (NAT), and Matching lists.

In this guide, we provide a complete breakdown of the 2021 exam, including subject-wise weightage calculations, the marking scheme, and direct links to download the JEE Advanced 2021 Question Paper with Solution PDF.

JEE Advanced 2021 Exam Pattern: Structural Overview and Distinctive Features

JEE Advanced 2021 maintained the rigorous two-paper structure but was conducted as a single-day examination unlike previous years. The examination pattern reflected IIT's commitment to testing multidimensional abilities including conceptual understanding, analytical reasoning, and application skills across Physics, Chemistry, and Mathematics.
