Tips to Prepare for NIOS Class 12 Chemistry Paper 2025
To prepare for the NIOS Class 12 Chemistry paper 2025, students are advised to adopt a balanced approach that covers both TMA and the Public examination syllabus. A few tips are listed below:
Begin by going through the bifurcated NIOS Class 12th Chemistry syllabus 2025. Identify which lessons are part of TMA and which are included in the public examination. This clarity will help with time management.
Topics such as Chemical Thermodynamics, Electrochemistry, Ionic Equilibrium, and Chemical Kinetics often carry significant weightage and require regular practice of numerical problems. Also, revise Organic Chemistry thoroughly.
Since TMAs contribute directly to the internal marks, completing and submitting them on time is important.
Solving NIOS 12th previous years’ question papers of Chemistry will help in understanding the NIOS 12th exam pattern, frequently asked questions, and time allocation during the exam.
Do regular revisions. Instead of last-minute cramming, revise small portions daily. Preparing formula sheets, reaction flowcharts, and summary notes will make revision faster.

According to the eligibility criteria for JEE Advanced, the candidates must have appeared in Class 12th and scored 75% aggregate marks. For the first time, you appeared in the CBSE Class 12 board exam in 2024, and in 2025, you appeared in the 12th examination from the NIOS board and scored 75%. Since NIOS is a recognised board, and you fulfil the aggregate marks, you are eligible to appear in JEE Advanced 2026 .
Yes, you can definitely appear for the 12th again through NIOS with PCM subjects.
This will make you eligible for JEE exams.
However, your previous PCMB degree will still hold validity. It won't be replaced or affected by the new NIOS certificate. You'll essentially have two 12th certificates.
Important Considerations:
- Time Management: Balancing NIOS studies and JEE preparation will be challenging.
- Eligibility Criteria: Ensure you meet the specific eligibility criteria for JEE, especially regarding age limits and other requirements.
- Exam Strategy: Develop a focused study plan to excel in both NIOS exams and JEE preparation.
Remember: While this is a potential path, carefully evaluate if it aligns with your long-term goals and if you're prepared for the academic and time commitment involved.
hope this helps you!!
