III. This Question paper has TWO parts: PART ‘A’ and PART ,8,
Part A
It consists of 25 objective type questions of one mark each. There is a negative marking of 0.33 marks for every wrong answer. The marks obtained by a candidate in this part will be used for resolving tie cases.
Part B
It consists of 50 objective questions of one mark each. There is no negative marking in this part.
3. AII questions are to be answered. Answers for these questions are to be entered on the OMR sheet, filling the appropriate circle against each question. For example, if the answer to aquestion is (d), it should be marked as below A B C D No additional sheets will be provided. Rough work can be done in the question paper itself and rough work sheets provided at the end of the booklet.
