The marking scheme awarded one point per correct response for objective-type questions, while descriptive responses received up to four marks depending upon the quality and depth of explanation. The total possible marks for the exam remained unchanged compared to previous years, standing at 90 marks.

Preparatory Strategies

To excel in the CBSE Class 12 Chemistry board exam, follow these general guidelines based on effective study habits and best practices adopted by successful students over the years:

1. Establish a consistent routine and divide your time effectively between different subjects.
2. Master basic concepts before moving forward. Make sure you fully comprehend each chapter instead of rushing through them.
3. Revise regularly and practice problems daily. Apply worked examples to solve similar ones on your own.
4. Practice past papers under timed conditions to familiarize yourself with the format and pacing requirements.
5. Build strong foundational knowledge first and then focus on application of principles.
6. Seek assistance when needed; clarify doubts with teachers, peers, or resources like textbooks and online tutorials.
7. Develop critical thinking skills by analyzing experiments and connecting theoretical concepts with real-world applications.

Keep in mind that diligent effort and consistent practice yield better results than cramming last minute. By following these tips, you can confidently tackle the 2023-24 CBSE Class 12 Chemistry board exam.
