Frequently Asked Questions

1.How many questions are in the COMEDK 2026 9th May Shift 1 paper?

This paper has 180 questions in total - 60 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 Shift 1?

COMEDK uses different question sets across shifts and sessions to maintain exam integrity, so this page reflects the specific paper administered in Shift 1 on 9th May 2026.

4.Where can I find the Shift 2 paper for the same date?

The COMEDK 2026 9th May Shift 2 paper is listed separately - you can switch to it from the "COMEDK Paper Wise PYQs" panel, under COMEDK 9th May 2026.

5.What is the structure of the COMEDK 2026 9th May Shift 1 paper?

The COMEDK 2026 9th May Shift 1 paper on MARKS has 180 questions, organised by subject:

  • Chemistry: 60 questions - 60 single-correct.
  • Mathematics: 60 questions - 60 single-correct.
  • Physics: 60 questions - 60 single-correct.
6.What is the difficulty level of the COMEDK 2026 9th May Shift 1 paper?

Each question on MARKS carries a difficulty rating. Of the 180 rated questions in this paper, 43 (24%) are easy, 135 (75%) are medium and 2 (1%) are hard. Subject wise:

  • Chemistry: 10 easy, 49 medium, 1 hard
  • Mathematics: 20 easy, 40 medium, 0 hard
  • Physics: 13 easy, 46 medium, 1 hard
7.Which chapters had the most questions in the COMEDK 2026 9th May Shift 1 paper?

The chapters with the most questions in each subject were:

  • Chemistry: Amines (5), Chemical Kinetics (5), and d and f Block Elements (5).
  • Mathematics: Probability (5), Application of Derivatives (4), and Differential Equations (4).
  • Physics: Electrostatics (6), Current Electricity (5), and Ray Optics (4).
8.Where can I find the solutions for the COMEDK 2026 9th May Shift 1 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.

9.How should I use the COMEDK 2026 9th May Shift 1 paper to check my preparation?

Set a timer, attempt the 180 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 COMEDK. Repeating this with other papers shows whether the same weak spots keep coming back.

10.Will the COMEDK 2026 9th May Shift 1 paper help me prepare for COMEDK 2027?

Yes. Every past paper shows the question styles and topics COMEDK 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.
