d) All questions carry equal marks.

e) Each question will have five options (A, B, C, D and E). If a candidate is attempting a question, she/he shall have to darken the appropriate circle A, B, C or D and if not attempting a question then, she/he shall have to darken E circle. If no circle is darkened, one fourth (0.25) mark shall be deducted.

f) One-fourth mark will be deducted for each wrong answer.

g) The examination paper will only be in English language.

h) The marks obtained by the candidates in the screening test will not be counted for final selection because it is only for short listing of category-wise candidates, for the subject knowledge test.
