GATE 2020 Agricultural Engineering Exam Pattern

The examination will be a computer-based with two types of questions- Objective type and Numerical Type. In Numerical Type, some numerical value has to be answered without any options provided.

Examination Mode Computer-based (Online)Test
No. of questions 65
Maximum Score 100
Duration 3 hours
Sections General Aptitude, Mathematics and Subject Specific
  • General Aptitude: 5 questions carry 1 mark each while the other 5 questions carry 2 marks each.
  • Mathematics: 5 questions carry 1 mark each and other 5 questions carry 2 marks each.
  • Agriculture Engineering: 20 questions carry 1 mark each. Also, the rest 25 questions carry 2 marks for every correct answer. Approximately equal weightage is given to the questions from 3 sections of GATE 2020 Agricultural Engineering Syllabus – Farm Machinery, Post-Harvest, Soil & Water and Irrigation & Drainage.

Note: There is no negative marking for Numerical Type. However, a  1/3rd negative marking will be done for both 1 and 2 marks question of MCQ for any wrong response
