Check the complete BSEB class 11 half-yearly biology paper analysis 2025-26.
The overall level of difficulty was easy to moderate, with no out-of-syllabus questions present.
Like other subjects, MCQ-type questions from biology were easy and score.
Questions were based on the NCERT; some of the questions were direct from the NCERT textbook.
For subjects like Biology, most of the questions are fact-based and directly picked from the NCERT textbook and diagrams. So study the NCERT line by line.
Study and revise from the previous year's biology papers to identify repeated and high-weightage questions.
Based on your previous year's weightage, prioritise studying or revising the highly weighted chapters/topics.
Do revision of your weak areas (chapter/topics) 2-3 times.
Have regular practice of diagrams and flowcharts, which also includes labelling them correctly, as diagram-based questions are highly scoring.
Make short notes of important definitions for quick revision.
Since wrong spelling can cost marks, for biology, it is very important to remember scientific terms and spellings correctly.
Do daily quick revision in different slots (20–30 mins) to memorise examples, different classification tables, etc.
Always write answers point-wise during practice, also keep them structured for better presentation and full marks.
