The 2026 paper successfully balanced the Class XI and Class XII curricula, with a notable shift toward application-based Physics and multi-step Organic Chemistry synthesis.
- Physics: Highly dominated by Electrodynamics and Mechanics; several questions utilized graphical analysis and multi-step derivations.
- Chemistry: Organic units emphasized name reactions and complex conversions, while Physical Chemistry remained calculation-heavy, especially in Electrochemistry.
- Biology: Followed NCERT lines with precision; the paper used "Match the List" and "Statement-based" formats to test conceptual depth in Genetics and Biotechnology.
