Benefits of Solving JEE Main Papers

The key benefits of solving previous years’ JEE Main papers are as follows:

  • You familiarise yourself with the exam pattern, type of questions asked, and marking scheme

  • Helps you evaluate the level of your preparation and performance 

  • You get to identify the areas of the syllabus you need more practice with

  • Your timing improves with regular practice 

  • Once you master old papers, you gain confidence and get exam-ready  

JEE Main 2020 Answer Keys

The National Testing Agency (NTA) has published the official answer keys for the JEE Main 2020 question papers on its official website. These answer keys were made available during the third week of January and the second week of September. They provide accurate solutions to all the questions from the exam. Essentially, candidates can verify the right answers and estimate their provisional JEE Main scores before the official results are declared by the exam conducting authority.

JEE Main 2020 Question Paper Pattern and Marking Scheme

The paper duration is 3 hours. Each correct answer earns 4 marks, and each wrong answer leads to a deduction of ¼ marks. Multiple answers with errors attract a ¼ mark deduction. Unattempted questions receive no marks. The paper consists of three subjects: Mathematics (25 questions at 4 marks each), Physics (25 questions at 4 marks each), and Chemistry (25 questions at 4 marks each), totaling 75 questions.
