  • Method of marking answers 

The nature of questions are OBJECTIVE TYPE. So, you need not write the answers on paper. For each question several suggested answers are given. You have to choose one response to each item.

The question paper will be in the Form of TEST BOOKLET. The booklet will contain questions bearing numbers 1, 2, 3…….etc. Under each item, Responses marked as (a), (b), (c), (d) will be given.

Your task will be to choose the correct answer. If you think there is more than one correct response, then choose what you consider the best response.

If you select more than one response, your response will be considered wrong.

You have to mark your response by completely blackening with black ball pen to indicate your response.

For each question for which a wrong answer has been given, one third (0.33) of the marks assigned to that question will be deducted as penalty.

If a question is left blank i.e. no answer is given, there will be no penalty for that question.
