What an Odisha CPET Paper Looks Like
The 2025 Chemistry paper (Subject Code 05) is a 16-page test booklet. Its cover gives 80 minutes and 100 marks for 100 multiple-choice questions, each with options (A) to (D), all compulsory, with +1 for a correct answer and −0.25 for a wrong one, marked on an OMR sheet. The questions are in English and run straight from 1 to 100 with no sections.
These questions are from the 2025 Chemistry paper. No answer key for 2025 is on this page, so each answer below is worked out from the question.

The first page of the 2025 Chemistry paper is all one-line recall or short calculations on atomic structure, bonding and ionic equilibrium. At 48 seconds a question in 2025, speed on such questions decides your score.
How to Use Odisha CPET Previous Year Papers?
- Practise at the current speed. In 2026 you got 1 hour 40 minutes for 100 questions, which is 60 seconds a question. Time yourself at that pace, even on older papers.
- Guess only when you can rule out an option. Since 2025 a wrong answer costs 0.25 mark. A blind guess among four options is worth about +0.06 marks, and ruling out one option lifts it to about +0.17.
- Start with your subject’s 2025 paper, because it has the same 100-question format. Then solve 2024 and 2023 (80 questions each) and the 2020 to 2022 papers for more practice.
- Compare the 2026 provisional and final keys. Both keys on the 2026 page cover every subject, so you can see which answers SSB changed after objections and avoid the same traps.
- Plan for May 2027. About six months are left. Solving one old paper of your subject every two weeks gets you through all six years before the exam.
