# GATE Aerospace Engineering Syllabus and Exam Pattern | Download GATE Aerospace eBooks

Aerospace Engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. GATE 2021 syllabus will include General Aptitude, Engineering Mathematics, and the topics from the Aerospace Engineering. The weightage of all the sections will be different. With the help of the GATE Aerospace Engineering syllabus, you can easily plan your studies and focus on topics that require more time.

In this article, you will find the complete guide on GATE Syllabus and exam pattern for Aerospace Engineering 2020-2021. We have provided the subject-wise list of GATE Aerospace Engineering Books.

## GATE Aerospace Engineering Syllabus 2020-2021

GATE 2021 Aerospace Engineering Syllabus will be divided into 6 sections. In each of the sections, the topics have been divided into two categories – Core Topics and Special Topics. As per the officials of GATE, 90% of the syllabus was from the core topics of aerospace while the remaining 10% was from special topics from the subject.

You should know that,

• 85% of the total questions are asked from the core subject and the remaining 15% questions are asked from the general aptitude section.
• You have to attempt 60 questions in a duration of three hours.
