HAL EXAM PATTERN, Previous Papers for all branches
The pattern of the recruitment test for HAL is given below:
The test consists of 160 qs. Duration is 150 min .
First section 20 qs related to General awareness and English
Second section 20 Qs related to mental ability and Quantitative ability.
Third section 120 Qs purely related to your Technical subjects .
There are five disciplines in which the question booklets are divided:
• Aeronautical
• Electrical and Electronics
• Mechanical and Production
• Metallurgy
• Computer Science
Paper Pattern
There are 160 questions in all the booklets. The questions are all objective types. There are 15 questions on General Awareness, 25 questions on General Engineering, 120 questions on the specific discipline. Each question carries 1 mark. So the total is 160.
There is no negative marking in the exam. Some further considerations are also made for the candidature. The candidates should have passed the final year of any of the specified branches. There is also a requirement of 60% marks in aggregate in all the semesters for general candidates and 50% marks for SC/ST Candidates.
