Exams are ongoing and the majority of students especially new students want to know how NATIONAL OPEN UNIVERSITY OF NIGERIA (NOUN) grading system is when it comes to calculating Exam Score and TMA.

In this article, I will teach you how to calculate NOUN exam Scores.

NOUN Exam is over 70

NOUN TMA is over 30

TOTAL: 100

TMA means Tutor Marked Assignment. For your registered course, you are entitled to 4TMA, of which you must submit before the end of the semester exam. After submitting, it will be graded over 10, but the best three TMA will be considered and be chosen, which makes it 30.

Let’s take CIT101 as a course case study.

Let’s say,

TMA 1 you scored 9.50

TMA 2 you scored 10.0

TMA 3 you scored 10.0

The three(3) TMA are 9.50, 10.0 and 10,0– which is equal to 29.50 over 30

Your TMA score is 29.50 over 30.

Now the question is, how do I calculate my exam score plus my TMA score?

It’s straightforward!!!!

You should note that all NOUN questions don’t Have the same number of questions, some have 100, 120, 150 and 35. The courses with 35 are most of the time MTH courses. 100 and 120questions are 2unit courses
150 questions are 3 unit courses

Anyway, let’s get into started…

For Example: (CIT101)
After the CIT101 exam, you checked your score, and you scored 95 out of 120 questions. And in your TMA for CIT101, as I said earlier, you scored 29.50/30.

To calculate your total score over 100, use this formula:

X/Y x 70/1
That is, let X = what you score in the exam, and Y = the total number of exam question, which simply means, EXAM SCORE divided by NUMBER OF EXAM QUESTION multiplied by 70.

Whatever your result is from the above calculation, you’ll now add it to your TMA.

Let’s do the math:

Exam score (X) = 80

Total number of exam question (Y) = 100

Therefore, it will be 80/100 x 70

The result is 56

Your exam score is 56

(N.B.: your TMA score is 29.50).


Now, to get final result add 56 exam + 29.50 TMA – Result is 85.5

Which means, CIT101 = A.

Also, note, you’ll follow the same way to calculate if your exam question is 100 or 150.

But in the case of 35 questions, all you need to do is multiply whatever you score by 2.

That is, if you score 20/35, it will be 20 x 2, which is equal to 40, meaning that you score 40/70. But sometimes, it will have been programmed in such a way the calculation would have been done. You’ll know if it is.

You’ll see your score over 70.

The National Open University of Nigeria (NOUN) adopts the general grading system, find it below:
0-39. — F
40-44 — E
45-49 — D
50-59 — C
60-69 — B
70-100 – A
