## JAMB Marking Scheme 2020

Now that we have known how many questions that JAMB set across each subject and the total number of questions set in all, let us now discuss how JAMB marks each subject.

Some persons may wonder, since English Language has 100 questions whereas others are having 50, does that mean it is scored higher than others are? The answer is No. All JAMB subjects carries equal marks no matter the number of questions that comes out from there.

So, English Language even though having 50 questions more when compared to other subjects is marked or graded on a 100% scale. The same also applies to other subjects.

Since there are four subjects that each candidate is required to write, the total aggregate of that score is on a 400 scale. That is 100 from Use of English, and 300 from the remaining 3 subjects.

### How To Calculate JAMB Score

Now that we know that JAMB marking scheme is on the 400 scale, let us now discuss how to calculate JAMB score.

For this, we will be taking four subjects as a case study so we can understand it properly. We will be using the following subjects:

- Use of English
- Mathematics
- Chemistry
- Physics

#### Calculating JAMB Score using an Example

- Let us assume that out of the 100 questions in Use of English, you were able to answer 55 correctly. That would give you 55/100=55%.
- Then for mathematics, you got 27 out of 50 questions. That would give you 27/50 * 100=54% or 54/100 (54 over 100).
- Then for Chemistry, you got 31 out of 50 questions correctly. That would give us a 31/50 * 100=62% or 62/100 (62 over 100).
- Lastly, for Physics, you got 37 out of 50 questions correctly. That is 37/50 * 100 = 74% or 74/100 (74 over 100).

To now get the total score, sum all your scores for each subject. That will now be 55+54+62+74=245. The JAMB score is 245/400 (245 over 400).

## Does JAMB Do Negative Marking?

As a bonus question, many candidate has wondered if JAMB does negative marking. But before we answer the question, let us establish what Negative marking scheme is all about.

**What is Negative Marking Scheme?**
