The Question Booklet Alpha Code allotted to you will be noted in the address list intended forobtaining your signature and also in the seat allotted to you in the Examination Hall.

If you get a question booklet where the alpha code does not match to the allotted alpha code in theaddress list/seating position,please draw the attention ofthe Invigilator IMMEDIATELY. .

The Question Booklet Serial Number is printed on the top right margin of the facing sheet. If yourquestion booklet is unnumbered, please get it replaced by new question booklet with same alphacode.

Write the question booklet alpha code in the space provided in Part B of the answersheet and darken the appropriate bubble.

The question booklet will be sealed at the middle of the right margin. Candidate should not openthe question booklet, until the indication is given to start answering.

Immediately after the commencement of the examination, the candidate should check that thequestion booklet supplied to him contains all the 100 questions in serial order.
