GATE AE Prep Portal provides all 1,300 official GATE AE AE previous year questions spanning 2007 through 2026. Every question includes detailed step-by-step mathematical derivations, official answer keys, KaTeX formula formatting, and subject-wise categorization.

How many full-length CBT mock tests are provided on the GATE AE portal?

The portal includes 41 full-length CBT mock tests specially crafted according to the official GATE AE 65-question / 100-mark blueprint with TCS-iON palette states, in addition to 20 official past exam papers from 2007 to 2026.

What core subjects are covered in the GATE Aerospace Engineering syllabus?

The official GATE AE syllabus covers 6 major technical sections: Aerodynamics & Gas Dynamics, Flight Mechanics, Propulsion, Aerospace Structures, Space Dynamics, and Engineering Mathematics, in addition to General Aptitude.

Is GATE AE Prep Portal free to use and available offline?

Yes, GATE AE Prep Portal is 100% free with zero fees. It is built as an offline-first Progressive Web App (PWA) with service worker caching and local IndexedDB data persistence, allowing aspirants to practice tests and revise formulas anywhere without an active internet connection.

What are the qualifying cutoff marks for GATE Aerospace Engineering (AE) across categories?

Historical GATE Aerospace qualifying cutoff marks typically range between 26.0 to 30.0 marks for General/Unreserved, 23.5 to 27.0 marks for OBC-NCL and EWS, and 17.0 to 20.0 marks for SC, ST, and PwD categories out of 100 total marks. Scoring 60+ marks generally secures an All India Rank (AIR) in the top 30, qualifying for M.Tech admissions at premier institutes like IISc Bangalore, IIT Bombay, IIT Madras, IIT Kanpur, and recruitment shortlists at ISRO/DRDO.

Is a virtual scientific calculator allowed in the GATE AE CBT exam?

Yes. Physical handheld calculators are strictly prohibited in the official GATE examination. Candidates must use the onscreen official TCS-iON virtual scientific calculator provided in the test interface. The GATE AE Prep Portal features an exact interactive replica of this official TCS-iON virtual calculator across all CBT mock tests and practice modes.

What is the chapter-wise subject weightage in GATE Aerospace Engineering?

Based on trend analysis across official GATE AE papers, the approximate marks weightage is: Aerodynamics & Gas Dynamics (~22-26%), Propulsion & Rocketry (~20-24%), Flight Mechanics (~18-22%), Aerospace Structures (~16-20%), Engineering Mathematics (13-15%), and General Aptitude (15%).

Can I crack GATE Aerospace Engineering with self-study without coaching?

Yes, absolutely. The GATE AE syllabus is rigorous and standard reference textbooks (Anderson, Nelson, Hill & Peterson, Megson) combined with thorough solving of 1,300 official PYQs (2007-2026) provide complete preparation.

Which subject has the highest weightage in GATE Aerospace Engineering?

Aerodynamics & Gas Dynamics carries ~22-26 marks, Propulsion & Rocketry carries ~20-24 marks, Flight Mechanics carries ~18-22 marks, and Aerospace Structures carries ~16-20 marks. Engineering Mathematics contributes 13-15 marks and General Aptitude is 15 marks.

What are the best reference books for GATE AE?

Key textbooks: Fundamentals of Aerodynamics & Introduction to Flight by John D. Anderson, Flight Stability & Automatic Control by Robert C. Nelson, Mechanics & Thermodynamics of Propulsion by Hill & Peterson, Aircraft Structures for Engineering Students by T.H.G. Megson, and Higher Engineering Mathematics by B.S. Grewal.
