AFCAT 1 2022 EKT Exam Pattern

Air Force Common Admission Test commonly known as AFCAT is a common entrance examination organized by Indian Air Force to select eligible cadets for multiple posts in Ground Duty and Flying Branch. AFCAT is conducted twice every year and millions of students appear in the examination to become part of prestigious organisation.

The conducting body has divided the AFCAT selection process 2021 into three phases –

AFCAT Online Exam for all candidates
EKT (for Technical candidates)
AFSB Interview
Final Selection after Medical Examination.

Exam	Subject	Duration	No. of questions	Max. marks
AFCAT	General Awareness, Verbal ability in English, Numerical ability and reasoning and military aptitude test	02 Hours	100	300
EKT(for Ground Duty technical branch only)	Mechanical, computer science and electrical &electronics	45 Minutes	50	150

The EKT exam is Engineer knowledge test. This test is only for candidates who opt for Ground duty technical branch. Candidates will be given 45 minutes to solve 50 questions in the EKT test. The maximum marks allotted to the exam are 150. The EKT test will carry questions from Mechanical, Computer Science and Electrical & Electronics.
