WAEC Biology Objectives ( Review) 2023/2024
The NECO biology questions and answers are divided into two sections (A & B). Where A is usually objectives with possibly 60 questions while B is always made up of 6 to 7 essay questions.
Below are the NECO biology questions and answers
1. Question: What is the function of the cell membrane?
Answer: The cell membrane serves as a protective barrier that controls the movement of substances in and out of the cell. It regulates the entry and exit of molecules, ions, and nutrients, maintaining the cell’s internal environment.
2. Question: What is the role of the endocrine system in the body?
Answer: The endocrine system is responsible for producing and releasing hormones into the bloodstream. These hormones act as chemical messengers, regulating various physiological processes such as growth, metabolism, reproduction, and mood.
3. Question: What is the process of osmosis?
Answer: Osmosis is the movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. It helps maintain water balance in cells and is crucial for processes such as nutrient absorption in plants and water regulation in animals.
4. Question: What is the function of white blood cells in the immune system?
Answer: White blood cells, also known as leukocytes, play a crucial role in the immune system. They help defend the body against pathogens, foreign substances, and infectious agents by identifying and destroying them or producing antibodies to neutralize them.
5. Question: What is the purpose of mitosis in cell division?
Answer: Mitosis is the process by which a single cell divides into two identical daughter cells. It is essential for growth, tissue repair, and asexual reproduction. Mitosis ensures that each new cell receives an identical set of chromosomes as the parent cell.

Tips to Get through NECO Biology Exam Questions 2023/2024
Preparing for the NECO Biology exam requires a systematic and focused approach. Here are some tips to help you get through the exam successfully:
1. Familiarize yourself with the syllabus
Start by thoroughly understanding the WAEC Biology syllabus for the 2023/2024 exam session. It will provide you with a clear outline of the topics and subtopics that could appear on the exam.
2. Organize your study materials
Gather all the necessary study materials, including textbooks, past question papers, and revision guides. Create a study schedule to allocate time for each topic and ensure comprehensive coverage.
3. Understand the concepts
Biology is a subject that requires understanding and not just memorization. Focus on understanding the underlying principles, processes, and relationships within each topic. Take time to grasp the key concepts before moving on to more complex details.
4. Use diagrams and illustrations
Biology often involves complex structures and processes. Utilize diagrams, illustrations, and labeled diagrams to help visualize and understand biological concepts. Practice drawing and labeling diagrams to enhance your comprehension and improve your ability to answer questions effectively.
5. Practice past questions
Past questions provide insight into the exam format and the types of questions that may be asked. Solve past question papers within a simulated exam environment to improve your time management skills and become familiar with the structure and wording of the questions.
6. Take note of keywords
Pay attention to the keywords used in the questions, such as “define,” “explain,” “compare,” or “describe.” Understand the specific requirements of each question and respond accordingly.
7. Develop a study group or seek assistance
Collaborating with classmates or joining a study group can be beneficial. Discussing concepts and solving questions together can help reinforce your understanding and provide different perspectives on challenging topics. If needed, seek guidance from your teachers or tutors to clarify any doubts or difficulties.
8. Practice biological terminologies
Biology often involves a vast array of specific terminology. Create flashcards or mnemonic devices to memorize important terms and their definitions. Regularly review and test yourself to ensure you have a strong grasp of the relevant vocabulary.
9. Take care of your well-being
Prioritize self-care, including proper sleep, a balanced diet, and regular exercise. Taking care of your physical and mental well-being will improve your focus, concentration, and overall performance during the exam.
10. Mock exams and self-assessment
As the exam approaches, attempt mock exams to simulate the actual test conditions. Evaluate your performance, identify areas of improvement, and revise accordingly. Self-assessment will help you identify your strengths and weaknesses, allowing you to allocate more time to challenging topics.
