I just wrote the UTME a couple of hours ago and i noticed (being my first time) that it has a Total score of 400mark for four multiple-choice subjects namely: Use of English Language, Government, English-Literature and Economics. The Use of English has a total of 100 questions all carrying 150marks, and the rest 3 subjects carry 50 questions each. If Use of English alone carries 150marks leaving behind 250marks for the rest three subjects, how is the total score of 400marks achieved?
