Frequently Asked Questions

1.How many questions are in the JEE Main 2023 29th January Morning Shift paper?

This paper has 90 questions in total - 30 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 morning 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 29th January 2023 morning shift.

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

The JEE Main 2023 29th January Evening Shift paper is listed separately - you can switch to it from the "JEE Main Paper Wise PYQs" panel, under JEE Main 29th January 2023.

5.What is the structure of the JEE Main 2023 29th January Morning Shift paper?

The JEE Main 2023 29th January Morning Shift paper on MARKS has 90 questions, organised by subject:
