GATE AE (Aerospace Engineering) provides admissions to the Master’s programme in Engineering and Master’s in Sciences in various IITs and other engineering institutes. GATE is one of the toughest exams for engineering aspirants to fulfill their dream of studying in an IIT.

The candidates who have studied AE in their B.Tech programme can also apply for M.Tech admissions in Mechanical or Automobile or Industrial as well. There is no specified age limit for applying for GATE AE.

GATE 2020 is scheduled on February 1, 2, 8 and 9, 2020 in online mode. There are questions based on general aptitude, engineering mathematics and core subject. There are MCQ and Numerical Answer type Questions in GATE AE Exam.

GATE AE Eligibility

Obtaining a B.Tech/B.E. /B.Sc. degree in Aerospace Engineering is not a pre-requisite to seek admissions in M.Tech programme through GATE. Candidates who apply for AE paper through GATE for M.Tech admissions into Mechanical, Automobile, Industrial, Biotechnology, Physics and Mathematics stream as well apart from admissions to Aerospace Engineering.

IIT Bombay considers B.Tech in Aerospace, Mechanical, Civil, Electrical, Electronics, Instrumentation streams for GATE AE Qualifiers admissions in M.Tech. International candidates with the B.Tech degree in the respective discipline or M.Tech/M.E. / M.Sc. in the required science subject are also eligible to apply.

GATE AE Paper Pattern and Syllabus

GATE AE Paper comprises three sections i.e. Engineering Mathematics, General Aptitude and Technical Questions. The other important features in GATE AE Exam Pattern are given below:

  • There are 65 questions in total to be solved in 180 minutes. The questions will be in English language only.
  • There are two types of questions in GATE AE Exam- Multiple Choice Questions (MCQ) and Numerical Answer Type Questions (NAT).
  • There are 10 questions from General Aptitude, 25 questions from Engineering Mathematics and 30 questions from the core subject
  • Out of the 30 questions from the core subject, there are 90% questions from the core topics and 10% questions from the special topics mentioned in GATE AE Syllabus.
  • A virtual calculator aids the calculation part in the exam. It contains all the necessary functions like power (root, square, nth power, nth root), trigonometric (direct and inverse), logarithmic etc.

GATE AE Admissions

GATE 2019 enables candidates to seek admission in their desired IITs or other renowned engineering institutes to the M.Tech/ M.E programme. The IISc, IITB, IITM and IITKgp offer direct admissions to the M.E. / M.Tech. Programme through GATE Scores.

The admission process for GATE is an online exam which will be held on February 1,2, 8 and 9, 2020. Candidates have to fill online applications to apply for the admission process and no hard copies must be sent.

IIT, Kanpur organizes a separate admission test (written) for admissions to the M.Tech. The ratio of the GATE Score and marks obtained in the admission test is 3:2 (approximately). For admissions, 70% weightage is given to GATE Scores and 30% is given to the admission test. The candidates with All India Rank up to 250 are called for the admission test.

The DIAT and IIST offer admissions to the master’s programme through admission test or interview. Candidates with AIR equal to or above 100 are called for the admission test or interview.

MIT, Chennai offers admissions through GATE and TANCET. The higher preference is given to the candidates who qualify GATE 2019 with good scores than TANCET qualifying candidates. As compared to other participating colleges MIT offers better opportunities. BIT, Mesra has released 12 seats for admissions to the M.Tech programme through GATE 2020.
