or torn or missing pages or questions etc. If so, get it replaced by a complete ‘Question Booklet’ of the

available series.

2. Write and encode clearly the Question Booklet Series A, B, C or D, Subject Code and

Register Number in the appropriate space provided for that purpose in the OMR Answer

Sheet. Also ensure that candidate’s signature and Invigilator’s signature columns are

properly filled in. Please note that it is candidate’s responsibility to fill in and encode

these particulars and any omission/discrepancy will render the OMR Answer Sheet liable

for Rejection.

3. You have to enter your Register Number in the

Question Booklet in the box provided alongside.

DO NOT write anything else on the Question Booklet.

4. This Question Booklet contains 100 questions. Each question contains four responses (answers).

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 most appropriate. In any case,

choose ONLY ONE RESPONSE for each question.

5. All the responses should be marked ONLY on the separate Answer Sheet provided and ONLY in

Black or Blue Ball Point Pen. See detailed instructions in the OMR Answer Sheet.

6. All questions carry equal marks. Attempt all questions. Every question for which wrong answer has been given by the candidate, 1/4th (0.25) of the marks assigned for that question will be deducted.

7. Sheets for rough work are appended in the Question Booklet at the end. You should not make any

marking on any other part of the Question Booklet.

8. Immediately after the final bell indicating the conclusion of the examination, stop making any

further markings in the Answer Sheet. Be seated till the Answer Sheets are collected and accounted

for by the Invigilator.

9. Questions are printed both in Kannada and English. If any confusion arises in the

Kannada Version, please refer to the English Version of the questions. Please note that in

case of any confusion the English Version of the Question Booklet is final.
