Neco Scoring | Grading System For Biology, Physics & Chemistry: An Updated Guide (2025/2026)
If you’re a science student preparing for the 2025/2026 NECO SSCE, understanding how Biology, Physics, and Chemistry are marked and graded is key to boosting your overall result. Whether you're aiming for Medicine, Nursing, Engineering, or any science-related course, knowing the NECO grading system gives you a huge advantage.
NECO Grading Scale for 2025/2026
NECO grades are based on the percentage of total marks scored. Below is the updated scale:
| Percentage (%) | Grade | Remark |
|---|---|---|
| 75 – 100 | A1 | Excellent |
| 70 – 74 | B2 | Very Good |
| 65 – 69 | B3 | Good |
| 60 – 64 | C4 | Credit |
| 55 – 59 | C5 | Credit |
| 50 – 54 | C6 | Credit |
| 45 – 49 | D7 | Pass |
| 40 – 44 | E8 | Pass |
| 0 – 39 | F9 | Fail |
NECO Biology Scoring Structure
NECO Biology is structured into two parts:
| Paper | Section | Marks |
|---|---|---|
| Paper I | Objective (50 questions) | 50 marks |
| Paper II | Theory & Essay | 100 marks |
| Total | 150 marks |
Your raw score is scaled down to 100%.
Example:
If you score:
-
35/50 in Objectives
-
65/100 in Theory
Total = 100/150 = 66.7% → Grade: B3
NECO Physics Scoring Structure
Physics combines theory and calculations. Here's how marks are distributed:
| Paper | Section | Marks |
|---|---|---|
| Paper I | Objective (50 questions) | 50 marks |
| Paper II | Theory (calculations, definitions) | 100 marks |
| Total | 150 marks |
Example:
Objective: 30/50
Theory: 55/100
Total = 85/150 = 56.7% → Grade: C5
NECO Chemistry Scoring Structure
Chemistry also follows the same format:
| Paper | Section | Marks |
|---|---|---|
| Paper I | Objective (50 questions) | 50 marks |
| Paper II | Theory (equations, reactions, etc.) | 100 marks |
| Total | 150 marks |
Example:
Objective: 38/50
Theory: 62/100
Total = 100/150 = 66.7% → Grade: B3
Summary Table – NECO Science Subjects Scoring Breakdown
| Subject | Objective Marks | Theory Marks | Total Raw Score | Scaled to 100% |
|---|---|---|---|---|
| Biology | 50 | 100 | 150 | ✅ Yes |
| Physics | 50 | 100 | 150 | ✅ Yes |
| Chemistry | 50 | 100 | 150 | ✅ Yes |
Tips to Score High in NECO Biology, Physics & Chemistry
Biology:
-
Study diagrams and labeling (e.g., plant cells, human organs).
-
Focus on photosynthesis, reproduction, and classification.
Physics:
-
Practice calculations (speed, velocity, energy, resistance, etc.).
-
Understand laws and principles (Newton’s laws, Ohm’s law).
Chemistry:
-
Memorize chemical equations and periodic trends.
-
Understand mole concepts, acid-base reactions, and organic chemistry basics.
Frequently Asked Questions (FAQs)
Q1: Are NECO science subjects hard to pass?
A: Not if you study smart. Many questions are repeated or follow familiar patterns. Use past questions.
Q2: How many marks do I need to get A1?
A: You need 75% and above.
Q3: Does NECO reduce marks for wrong answers?
A: No. NECO does not use negative marking.
Q4: Can I study Medicine without A1 in Physics or Chemistry?
A: Most universities require at least Credit (C6) in Physics, Chemistry, Biology, English, and Math.
Final Thoughts
Scoring high in NECO Biology, Physics, and Chemistry is all about mastering the format and working with the right materials. Use this scoring system to track your performance during practice. Aim for 65% and above in each paper to be in a safe zone for competitive courses.
Pro Tip: Use the scoring table to set weekly targets and evaluate your NECO practice tests.
