Vineeta Kadwane, Subject matter expert from Lancers Army Schools said "The 2026 CBSE Class 12 Biology exam, held on March 27, 2026, has favoured conceptual depth over rote memorization. Many questions were  "tricky" and required a relationship between two facts, rather than just knowing the facts themselves. Instead of just asking for definitions, questions focused on interpreting Pedigree charts and solving Mendelian cross numericals. This was a "thinking student's paper." Because CBSE uses step-marking, students who attempted questions with correct logical flow and diagrams are still expected to score well."
