As per the initial reports from teachers and students, the Biology exam conducted by CBSE for class 12 was bit tricky. The experts have opined that the paper was application based and was above average in terms of difficulty level. Some of the one markers and sub-parts of three markers and five markers were ticky to understand. Students who had prepared through the NCERT book and whose concepts were clear would have found the paper to be easy. Overall it was a well balanced paper.
