Some teacher first mark one question for every student and then move on to the second question until the last question. Others mark all questions for one student and then move to the next student until the last question paper. Which of the 2 methods is better than the other
In general it is way better to mark one question after the other and not the whole script/test at once, This way you are not influenced by a number of bad answers and get biased to grade the next one. In practice this is also more work. I guess with more than 20 or 30 students to grad most teachers will mark the whole test/script.
I think first method is appropriate. But before checking the answer sheets you should framed model answer of all questions and then you can categorize answers in certain categories.
