(20 + 5) Question for each paper, i.e, 75 no. of questions to be answer in totality. Total marks for JEE (main) is 300. Out of 25 questions per paper, 20 questions will be MCQ type and 5 questions will have to fill with numerical value.

After completion of full syllabus of IIT-JEE and thorough revision of each and every chapter for Physics, Chemistry and Mathematics.
When you practice previous years question papers, you tend to get a fair idea of the kind of questions that may be asked in real examination, tricks involved, topic-wise marks distribution, etc. This helps you build confidence and helps you to make a strategy, how to divide your time efficiently and enhance your performance in PHYSICS, CHEMISTRY and MATHEMATICS.
Though many of the students feel that this is a waste of time, given that no question is ever repeated except in rare cases in IIT JEE Mains but what one conveniently ignores that every year the pattern of the question paper remains almost the same. When you practice questions that are based on concepts that you have studied earlier, you test your ability to recall the topics, application of your knowledge, innovate and solve problems.

When you go through the Last 40 years question papers for IIT-JEE Main, you will be able to figure out the important topics and for which you must revise respective Topics for PHYSICS, CHEMISTRY and MATHEMATICS. This will save your valuable time in the long run and keep yourself focused towards the real exam of JEE (main) / IIT-JEE.
