11th Class Biology Paper Pattern 2025

The Biology paper is divided into two parts — Objective and Subjective.

1. Objective Part (17 Marks)

This part consists of 17 multiple-choice questions (MCQs) — one from almost every chapter.
To score well here, make sure to:

Revise key terms, functions, and processes.
Focus on scientific names, classifications, and enzymes.
Solve past MCQs from guidebooks and model papers.

2. Subjective Part (68 Marks)

The subjective portion is further divided into short questions and long questions.

a) Short Questions (36 Marks)

Short questions are usually spread across three sections.
Each section includes 8–10 questions, and you’ll attempt a specific number from each.

Expected distribution (2025):

Section I: Chapters 1–4
Section II: Chapters 5–8
Section III: Chapters 9–11

Focus on definitions, reasoning-type questions, and differences (e.g., mitosis vs. meiosis, prokaryotic vs. eukaryotic cell).

b) Long Questions (32 Marks)

The long questions test your understanding of processes, systems, and mechanisms. Usually, you’ll get five questions and must attempt any three, each carrying 10–11 marks.

Commonly paired chapters for long questions include:

Q1: Chapter 1 + Chapter 2 (Cell Biology & Biological Molecules)
Q2: Chapter 5 + Chapter 6 (Kingdoms & Plant Physiology)
Q3: Chapter 9 + Chapter 10 (Digestion & Respiration)

Make sure to practice labeled diagrams — they often carry 2–3 marks.

Chapter 1 – Cell Biology
Chapter 2 – Biological Molecules
Chapter 5 – Kingdom Prokaryotae & Protista
Chapter 8 – Nutrition
Chapter 9 – Digestion
Chapter 10 – Respiration

Prepare these thoroughly for both long and short questions.

Smart Study Tips

Understand, don’t cram. Biology is concept-based; visualize processes instead of memorizing lines.
