2. You have to enter your Roll No. on the Test
Booklet in the Box provided alongside. DO
NOTwrite anything else on the Test Booklet.
3. The Test Booklet contains 100 questions. Each question comprises four answers. YoU
have to select the correct answer which you want to mark (darken) on the Answer Sheet U,
(OMR Sheet). ln any case choose ONLY ONE answer for each question. lf more than rn
one answer is darkened, it will be considered as wrong.
4. You have to mark (darken) all your answers only on the OMR Answer Sheet using
r
BLAGK BALL POTNT PEN provided by the State Selection Board. You have to do rough
work only in the space provided at the end of the Test Booklet. See instructions in the
Answer Sheet.
5. All questions carry equal marks i.e. of one and half mark for each correct answer and each
wrong answer will result in negative marking of 0.50 mark.
6. Before you proceed to mark (darken) the answers in the OMR Answer Sheet to the
questions in the Test Booklet, you have to fill in some particulars in the Answer Sheet as
per the instructions in yourAdmit Card.
7. On completion of the examination, you should hand over the original Answer Sheet
(OItlR Sheet) issued to you to the lnvigilator before leaving the Examination Hall. You are
allowed to take with you the candidate's copy (carbon copy) of the OMR Answer Sheet
along with the Test Booklet for your reference.
