Nature of Questions

Nature of JEE Main 2021 Mathematics Questions

In JEE Main 2021, candidates will have to answer two types of questions in the paper. The first type is MCQs and the second type is Non-MCQ or Numeric Value questions. 

  • Multiple Choice Questions: In MCQs, candidates will get 4 options to answer the question. Candidates have to select one correct answer. 
  • Numeric Value or Non-MCQs: In Numeric Value questions there will be no options provided and candidates have to enter their answer either an integer or decimal value.
  • Shortcut Method Questions: There might be some questions or topics in which you can easily apply some shortcut methods to reach directly to the answer. But for that you must know such tricks and also you have to solve more and more questions so that you can identify such questions in the examination.
  • Formula Based Questions: In JEE Main Mathematics paper some of the questions will be directly based on formulas. To solve these questions knowledge of formulas is very important. By applying the formula candidates can get the right answer. Such questions may not require lengthy calculations and can be easily & quickly. 

Important Topics

JEE Main 2021 Mathematics: Important Topics 

It is very important for candidates to cover all the topics of the JEE Main 2021 Syllabus prescribed by NTA.

How many non mcq questions are asked in maths?
manika gupta

Hi, Total 75 questions are asked in JEE Mains, 25 questions from each subject – Physics, Chemistry and Maths. The JEE Mains weightage for each chapter is different, although the total marks are equal for all the three sections. Students should also note that for each multiple-choice or numerical based question marked correctly, they will be awarded four marks, and for a wrong MCQ answer, one mark will be deducted. However, there is no negative marking for a wrong numerical answer.

Which topic in maths is highly scoring?
manika gupta

Hi, The most scoring topic under integral calculus is arguably the chapter on definite integrals. It involves a minimal set of formulae which if mastered can give excellent results in JEE. Integral Calculus by Amit Agarwal is an excellent book with a good balance of theory and problems.
