What to Expect in NECO 2025 Physics Exam
The NECO Physics paper is divided into two main parts:
-
Objective (OBJ) – 50 Multiple Choice Questions
-
Essay – Long answer questions testing deep understanding
Each part is designed to evaluate students’ understanding of core physics concepts and their application in solving real-life problems.

NECO 2025 Physics Essay Sample Questions and Answers
These long-answer questions help test deeper knowledge. Below are samples based on the NECO syllabus.
Question 1:
Explain with diagram how a simple electric bell works.
Answer:
An electric bell works based on the principle of electromagnetism. When the switch is pressed, current flows through the electromagnet, attracting the hammer towards the gong. As the hammer moves, it breaks the circuit and the electromagnet loses magnetism. The hammer returns and the process repeats rapidly, producing a ringing sound.
Diagram: Candidates should draw a labeled diagram showing the coil, hammer, gong, and switch.
Question 2:
State Ohm’s Law and explain how it applies in electrical circuits.
Answer:
Ohm’s Law states that the current (I) flowing through a conductor is directly proportional to the voltage (V) across it, provided the temperature remains constant. That is,
V = IR,
where R is resistance.
This law helps in calculating unknown values in a circuit. For example, if voltage and resistance are known, the current can be calculated.

Common Mistakes Students Make in NECO Physics and How to Avoid Them
Many candidates lose marks in Physics due to avoidable errors. Here are some common mistakes and how to avoid them:
1. Ignoring Units
Physics is a quantitative subject. A correct numerical answer without the correct unit is incomplete.
Tip: Always include correct SI units, such as meters (m), seconds (s), and Newtons (N).
2. Poor Diagram Labeling
Students often lose marks by submitting diagrams without labels or with incorrect labels.
Tip: Practice drawing and labeling common diagrams like mirrors, lenses, transformers, and electric bells.
3. Wrong Formula Application
Using the wrong formula can cost you the entire mark for a question.
✅ Tip: Memorize formulas but focus more on understanding when and how to use them.
4. Not Managing Time
Physics essay questions can be time-consuming. Spending too much time on one question may lead to rushing through others.
Tip: Practice under timed conditions before the exam to develop speed and accuracy.

Mini FAQ: NECO 2025 Physics
Q1: Can I rely only on past questions?
Answer: No. Past questions help, but you also need to understand concepts because NECO can change how questions are asked.
Q2: How do I prepare for NECO Physics practical?
Answer: Learn how to use lab instruments like the metre bridge, ammeter, voltmeter, and prism. Understand how to take readings and plot graphs.
Q3: Will NECO Physics be difficult in 2025?
Answer: Difficulty varies per candidate, but with consistent study and good materials, you can score well.
Q4: Is it okay to join Telegram or WhatsApp groups for NECO expo?
Answer: No. These groups often engage in exam malpractice, which is illegal and a violation of Google AdSense policy. Rely on official and ethical study materials.
Final Advice for 2025 NECO Physics Candidates
