  1. I disagree with your comments on negative markings. I believe JAMB does negative markings. I took JAMB last year and I scored 67 each in Economics and Government. Why would these marks be odd if there is no negative marking? There are 50 questions. The total score mark is 100. So it is logical that each question carries 2 marks. Therefore all scores should be even and not odd numbers. There is negative marking because JAMB removes one mark for every wrong question.

    • @ David, from a reliable source, I can tell you that JAMB does not adopt any negative marking scheme. There are many issue that may arise which can lead to marks miscalculations or wrong score presentation. It might be from human error, OMR machine error even personal grudge on the part of the examiner, who handles the answer script. This forms the highpoint of interest that prompted JAMB to adopt a more reliable computer based testing system. With CBT, all marks will be auto-calculated without any mistake. This year’s JAMB CBT will be different. I hope this helps.

      • For every one complaining about negative marking… jamb dosen’t mark negatively.. what they actually do is mark with percentage… they have been dowing this since PPT days and are still doing it with the CBT. For the CBT, there are 60 English questions, 40 questions each for other subjects.. that’s a total of 180 questions. But it’s being marked over 400. How?… let’s say u scored 32 out of 60 questions in English, they will mark: (32÷60)×100.. this gives u 53.3% out of 100% obtainable. They approximate it to 53% which is why all mark can’t be even numbers or only odd number because they use percentaget and not 2 marks or 1 mark or negative marking per question as people presumed.

  2. It is obvious that jamb adopts nagative marking scheme of -1 on every wrong answer. In the this conclude 2015 cbt, even 2014 whic I took cbt, I scored nagative marks in biology and physics, why? Besides, by the nature of the exam, I scored lower than it should be. I strongly argue that jamb adopts nagative marking.
