Note :-

1. Exam Duration: 2.30 hours
2. Exam Type: Multiple Choice Questions
3. Negative Marking: For every wrong answer one-third of the marks prescribed for that particular question shall be deducted. Wrong answer means an incorrect answer or multiple answers.
4. Each question has five options. Darken only one circle indicating the correct answer using a BLUE BALL POINT PEN.
5. It is mandatory to fill one option for each question.
6. If a question is not attempted, darken circle '5'. If none of the five circles are darkened, 1/3rd of the marks will be deducted.
7. 10 minutes of extra time is provided to ensure all questions are answered. Candidates who do not darken any of the five circles in more than 10% of the questions will be disqualified.
