Frequently Asked Questions

1.How many questions are in the JEE Main 2020 6th September Evening Shift paper?

This paper has 75 questions in total - 25 each from Chemistry, Mathematics, and Physics.

2.Can I practise questions from just one subject?

Yes. Use the Chemistry, Mathematics, and Physics tabs at the top of the page to jump directly to that subject's question set within this shift.

3.Is this the same paper for all students who appeared in the evening shift?

JEE Main uses different question sets across shifts and sessions to maintain exam integrity, so this page reflects the specific paper administered in the 6th September 2020 evening shift.

4.Where can I find the morning shift paper for the same date?

The JEE Main 2020 6th September Morning Shift paper is listed separately - you can switch to it from the "JEE Main Paper Wise PYQs" panel, under JEE Main 6th September 2020.

5.What is the structure of the JEE Main 2020 6th September Evening Shift paper?

The JEE Main 2020 6th September Evening Shift paper on MARKS has 75 questions, organised by subject:

Open any question on this page. Its page shows the correct answer and, where one is available, the worked solution. A downloadable PDF of the whole shift is coming soon.

10.How should I use the JEE Main 2020 6th September Evening Shift paper to check my preparation?

Set a timer, attempt the 75 questions as you would in the exam, and only then open the answers. Note which subjects and chapters cost you the most marks, and revise those first using the chapter-wise practice for JEE Main. Repeating this with other papers shows whether the same weak spots keep coming back.

11.Will the JEE Main 2020 6th September Evening Shift paper help me prepare for JEE Main 2027?

Yes. Every past paper shows the question styles and topics JEE Main has asked before, and a solved paper gives you a realistic benchmark for speed and accuracy. Use it along with the other papers to spot the chapters that keep returning.
