You’re right to point out that “Class 12” is a broad term, and both CBSE and ISC boards have specific syllabi. My previous Table of Contents was a comprehensive overview that aimed to cover most common topics, but for a truly effective “Mastering Physics Numericals” book, it’s crucial to align it as closely as possible with the current syllabi for the 2024-25 academic year.

Based on the latest CBSE and ISC Class 12 Physics syllabi, here’s a revised and more accurate Table of Contents, highlighting the key units and chapters where numerical problems are prominent. I’ve also noted some key differences or emphasis for each board where applicable.
