Exam Pattern for GATE 2019 Agricultural Engineering (AG)
It consists of basically two type of questions namely
- Multiple Choice Questions which are objective type questions each having 4 choices of answers. They are of 1 or 2 marks in all Sections. It also includes negative marking. Hence, for each correct answer 1 will be added and for each incorrect answer 0.33 mark will be deducted and for each 2 marker question correct answer gives 2 marks and incorrect answer deducts 0.66 marks.
- Numeric Answer Questions are different from Previous MCQs. They don’t include any choices they have answers which are real numbers which are to inserted by virtual keypad appeared on the monitor via mouse. They also carry 1 or 2 marks in different sections. No negative marking is there for the same.
The paper pattern is as follows
| TOPICS | MARKS DISTRIBUTION |
| Technical Section | 70 marks |
| General Aptitude | 15 marks |
| Engineering Mathematics | 15 marks |
| Total Marks | 100 marks |
| Total Questions | 65 questions |
| Time Duration | 3 hours |
