IMMEDIATELY AFTER THE COMMENCEMENT OF THE EXAMINATION, YOU SHOULD CHECK THAT
THIS TEST BOOKLET DOES NOT
HAVE ANY UNPRINTED OR TORN OR MISSING PAGES OR ITEMS,
ETC. IF SO, GET IT REPLACED BY A COMPLETE TEST BOOKLET.
Please note that it is the candidate's responsibility to encode and fill in the Roll Number and Test
Booklet Series Code A, B, C or 13 carefully and without any omission or discrepancy at the
appropriate places in the OMR Answer Sheet. Any omission/discrepancy will render the Answer
Sheet liable for rejection.
You have to enter your Roll Number on the
Test Booklet in the Box provided alongside.
DO NOT write anything else on the Test Booklet.
This Test Booklet contains 150 items (questions). Each item comprises four responses (answers). You
will select the response which you want to mark on the Answer Sheet. In case you feel that there is
more than one correct response, mark the response which you consider the best. In any case, choose
ONLY ONE response for each item.
You have to mark all your responses ONLY
on the separate Answer Sheet provided. See directions
in the Answer Sheet.
All items carry equal marks.
Before you proceed to mark in the Answer Sheet the response to various items in the Test Booklet,
you have to fill in some particulars in the Answer Sheet as per instructions sent to you with your
Admission Certificate.
After you have completed filling in all your responses on the Answer Sheet and the examination has
concluded, you should hand over to the Invigilator
only the Answer Sheet.
You are permitted to
take away with you the Test Booklet.
Sheets for rough work are appended in the Test Booklet at the end.
Penalty for wrong answers:
THERE WWI BE PENALTY FOR WRONG ANSWERS MARKED BY A CANDIDATE.
There are four alternatives for the answer to every question. For each question for which a wrong answer
has been given by the candidate, one-third (0.33) of the marks assigned to that question will be
deducted as penalty.
If a candidate gives more than one answer, it will be treated as a wrong answer even if one of the given
answers happens to be correct and there will be same penalty as above to that question.
If a question is left blank, i.e., no answer is given by the candidate, there will be no penalty for that
question.
