What Is JAMB Score?

JAMB score is the total mark a student can achieve in the UTME exam, ranging from 0 to 400. This score influences the likelihood of gaining admission to a specific University, Polytechnic, or College of Education.

The JAMB score per question represents the marks awarded for each correct answer in the exam. With 180 questions in total, each carrying equal weight, the JAMB examination has a cumulative score of 400, distributed equally across the four subjects, each contributing 100 marks.

What is JAMB Marking Scheme?

The Jamb Marking scheme to my understanding is an organised marking system where JAMB’s examiners award one mark for each correct answer and impose negative marking for incorrect answers, aiming to discourage guessing by candidates.

What is JAMB Grading System?

The JAMB grading system is based on UTME performance, with a maximum score of 400 (100 points per subject). Grading is as follows:

• 75% and above: Excellent
• 65% – 74%: Very Good
• 50% – 64%: Good
• 45% – 49%: Fair
• 40% – 44%: Pass

Below 40%: Fail The aggregate score determines eligibility for admission, but institutions may set higher cut-off marks than the JAMB minimum pass mark.

How is the JAMB Exam Marked?

JAMB employs a computerized system, utilizing the “item response theory” (IRT) for marking the UTME. Specifically, they apply the “one-parameter logistic model” (1PLM) within IRT.

This statistical model assesses a candidate’s ability based on their responses, assuming the likelihood of a correct answer hinges on both question difficulty and the candidate’s ability.

The IRT model ensures fairness and reliability by incorporating questions of different difficulty levels and accommodating candidates with varying abilities.

For Instance, the Use of English in UTME carries a total of 100 marks, distributed across three sections with a total of 60 questions. Here’s the breakdown:

Section A: Comprehension/Summary Questions

• Comprehension Passages: 5 questions x 3 marks each = 15 marks
• Cloze Passage/Register: 10 questions x 2 marks each = 20 marks
• Reading Text: 10 questions x 1 mark each = 10 marks
  • Section A Total Score: 45 marks

Section B: Lexis and Structure Questions

• Sentence Interpretation: 5 questions x 2 marks each = 10 marks
• Antonyms: 5 questions x 2 marks each = 10 marks
• Synonyms: 5 questions x 1 mark each = 5 marks
• Basic Grammar: 10 questions x 2 marks each = 20 marks
  • Section B Total Score: 45 marks

Section C: Oral Forms (Test of Oral)

• Vowels: 2 questions x 1 mark each = 2 marks
• Consonants: 2 questions x 1 mark each = 2 marks
• Rhymes: 2 questions x 1 mark each = 2 marks
• Word Stress: 2 questions x 1 mark each = 2 marks
• Emphatic Stress: 2 questions x 1 mark each = 2 marks
  • Section C Total Score: 10 marks

Overall UTME Use of English Total Marks: 100 and your JAMB score is determined by the number of correctly answered questions in each subject, multiplied by the respective marks for those questions.

How Is The JAMB Score Calculated?

For instance, in JAMB UTME Use of English, consisting of 60 questions, Obi answered a total of 40 questions correctly. The breakdown of Ada’s score is as follows:

Obi scored a total of 60 marks in the JAMB UTME Use of English, which comprises 60 questions. In Section A, He earned 20 marks by correctly answering questions in Comprehension Passages, Cloze Passage, and Reading Text. Section B contributed 30 marks to his total, with correct responses in Sentence Interpretation, Antonyms, Synonyms, and Basic Grammar.

Obi secured 10 marks in Section C by answering all questions correctly in Vowels, Consonants, Rhymes, Word Stress, and Emphatic Stress. Overall, Obi’s achievement is the sum of these section scores, indicating her performance in the Use of English section.

Except for English (Use of English) in JAMB UTME, which has 60 questions, other UTME subjects each have 40 questions. Each question is scored 2.5 marks, resulting in 100 marks per subject. For the three subjects (Mathematics, Physics, and Chemistry), the total marks are 300 (40 x 2.5 + 40 x 2.5 + 40 x 2.5), and when combined with English (100 marks), the overall total is 400 marks.

For example, if Obi answered 30 questions correctly in each of these three subjects, his score in each subject would be 75 marks. Thus, Obi’s total mark for Mathematics, Physics, and Chemistry would be 75 + 75 + 75 = 225 marks.

Therefore, Obi’s JAMB UTME score is the sum of his marks in Use of English (60) and the three other subjects (225), resulting in a total score of 285 out of 400 marks.
