Frequently Asked Questions
1.How many questions are in the JEE Main 2023 25th 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 25th January 2023 morning shift.
4.Where can I find the evening shift paper for the same date?
The JEE Main 2023 25th January Evening Shift paper is listed separately - you can switch to it from the "JEE Main Paper Wise PYQs" panel, under JEE Main 25th January 2023.
5.What is the structure of the JEE Main 2023 25th January Morning Shift paper?
The JEE Main 2023 25th January Morning Shift paper on MARKS has 90 questions, organised by subject:
- Chemistry: 30 questions - 20 single-correct and 10 numerical-value.
- Mathematics: 30 questions - 20 single-correct and 10 numerical-value.
- Physics: 30 questions - 20 single-correct and 10 numerical-value.
6.What is the difficulty level of the JEE Main 2023 25th January Morning Shift paper?

Yes. 19 of the 90 questions in this paper are marked on MARKS as outside the current syllabus. You can still practise them for the concept, but they are a lower priority if you are short on time.
9.Where can I find the solutions for the JEE Main 2023 25th January Morning Shift paper?
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 2023 25th January Morning Shift paper to check my preparation?
Set a timer, attempt the 90 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 2023 25th January Morning 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.
