The Central Board of Secondary Education (CBSE) conducted the Class 12 Biology exam from 10:30 am to 1:30 pm at various centres across the country today.

According to subject experts, questions were "easy and direct." Most of them were concept-based and followed standard processes from textbooks. Assertion–reasoning questions were relatively easy, while case-based study questions were grounded in practical, real-life applications.

However, one or two questions were "tricky." Those questions needed careful reading, and some students found them slightly confusing. The social or application-based questions were also quite straightforward.

"They didn’t require too much deep thinking or analysis, but rather a clear understanding of concepts," a subject expert from JAIN International Residential School, Bengaluru said.

CBSE LOC registration from 2026-27

CBSE has made it mandatory for students to provide APAAR IDs while submitting their board examination registration forms. This decision follows the board’s observation that by the 2025–26 academic session, less than half of the students in affiliated schools had secured an Automated Permanent Academic Account Registry (APAAR) ID.

At its governing body meeting in December, the board also approved the introduction of two levels of examinations for Mathematics, Science, and Social Science in Class 10, which will be implemented from the 2028 academic session onward.
