CBSE biology analysis: "balanced distribution of questions"

A balanced distribution of questions was found in the biology paper, including questions that were easy, average and difficult. The paper had a well-defined focus for a diverse group of students. The questions in sections B, C, and D were moderately challenging, but Part E was mostly direct. Despite following the CBSE 2023 biology sample paper's format, the paper also required technical application to answer the questions. Students who have thoroughly prepared with NCERT books will do well in the exam.
