GATE 2019 – Syllabus of Aerospace Engineering

GATE 2019 – Graduate Aptitude Test in Engineering (GATE) is a national level examination, and GATE 2019 exam is managed by the IIT, Madras. In relevant branches of science, it is conducted to offer admission into M.Tech/M.Sc in engineering/ technology/ architecture and P.hD. GATE 2019 Mock Tests have been released.

The topics have been divided into two categories into each of the following subjects. On core topics, the corresponding sections of the question paper will contain 90% of their questions and the remaining 10% on Special Topics.

About Aerospace Engineering

Few tips to crack GATE 2019

  • Begin from basics read everything from standard books but do make notes of whatever you read in a separate notebook.
  • Make a practice of learning previous year questions will fetch you 40–45 marks
  • Create a formula notebook and note all formulas of your course in it (approx 2000-2500 methods) revise it periodically.
  • In a parallel manner, all above four steps should be executed together
