The JEE Advanced is one of India's hardest engineering entrance examinations, which focuses on testing conceptual knowledge and solving problems. Matrices and Determinants are an important chapter in the mathematics syllabus for JEE Advanced because they are also used in algebra, calculus, and coordinate geometry.
Based upon past year questions, the topic Matrices and Determinants made up an average of around 8% -10% of the total marks in mathematics, although weightage may vary every year as per examination pattern. In mathematics, typically 2-3 questions are drafted on this topic in JEE Advanced, where the total marks are in the range of about 8-12 overall.

It has a good weightage in the Mathematics section and can be tested in objective type as well as numerical based questions. A considerable understanding of the concepts of PNC can help solve difficult problems and can improve your score in the exam.
Q4. What is the toughest subject in JEE?
Answer. The hardest subject in JEE differs from person to person. Physics is often considered the toughest exam by many as the hardest subject because it has so many concepts and problem-solving/application-based questions to focus on (especially in Mechanics, Electrodynamics, and Modern Physics). Some students think of Mathematics or Chemistry (especially Organic Chemistry) as the hardest subject, depending on the student's strengths/weaknesses. The bottom line is that the hard subject depends on how each student prepares and understands the material.
Q5. Is matrices and determinants a hard chapter?
Answer. Matrices and Determinants can be tough for some students because it is more of an abstract idea as well as one must know what the properties of the determinants are, what are the applications and operations of the matrices, etc. However, knowing that matrices and determinants are a part of your JEE preparation, with adequate practice and understanding of the basic principles, this chapter is easier. It is an important topic in JEE Advanced, and understanding and mastering it can increase your Mathematics score.Absolutely, matrices and determinants are crucial topics for JEE Advanced.
