At this stage, it is crucial to stick to the NCERT Biology textbooks and your handwritten short notes. Do not waste time with reference books or additional resources.
The NCERT is the foundation of NEET Biology and will help you understand the core concepts and focus on important details. Carefully go through each chapter and underline or highlight important definitions, facts, and examples.
Short notes are especially useful for quick revision. These notes, written in your own handwriting, will provide a concise summary of each chapter and will be more useful than reading from textbooks during the last-minute revision. Use these notes to quickly revise key concepts and avoid unnecessary reading.
Biology in NEET is not only about theory but also about understanding and biology drawing diagrams. Diagrams are an essential part of the exam, and practicing them during your last-minute revision can help you score well.
Some of the important diagrams to focus on are:
Structure of DNA and RNA: Understanding the double helix structure and the functions of different components is vital.
Human Heart and Brain: You must be able to label the parts of the heart and brain, and understand their functions.
Parts of a Flower: The structure of a flower and its reproductive organs should be clearly understood.
Xylem and Phloem: These diagrams are important in Plant Physiology, and knowing their structure and function is key.
Photosynthesis and Respiration: These processes are central to both plant and animal physiology, so practice drawing and labeling diagrams related to these processes.
Spend time drawing these diagrams yourself without looking at the reference to test your memory and improve your recall during the exam.
In NEET Biology, many questions are based on definitions and key terms. These terms might be simple but remembering them can make a significant difference. Set aside time during each revision session to go over definitions from various chapters.
Important terms to revise include:
Gene, Allele, Mutation: These basic genetics terms are frequently tested.
Hormones like Insulin, Thyroxine: Understand their functions and how they regulate bodily processes.
Enzymes: Know the types of enzymes and their roles in digestion and metabolism.
Immunity and Antibodies: Revise the immune system and the different types of immunity (active and passive).
To make your last-minute revision effective, practice as many multiple-choice questions (MCQs) as possible. MCQs are an integral part of the NEET exam, and solving them will help you improve your accuracy and speed.
Start by solving questions from the chapters you have already revised. You can refer to:
Previous Year NEET Papers: These will give you a good idea of the type of questions asked.
MCQ Books Based on NCERT: These books are designed to follow the NEET pattern closely.
NEET Mock tests are an essential part of last-minute preparation. Taking full-length NEET mock tests will help you simulate the actual exam environment. It is important to follow the exam pattern while taking these tests to build endurance and improve your time management skills.
Take at least 2-3 mock tests in the final week before the exam. After each test, spend time analyzing your mistakes and focus on your weak areas. Mock tests will help you identify your strengths and weaknesses, and you can use this feedback to guide your remaining revision.
