**AFCAT 02/2021 Recruitment Syllabus, Exam Pattern**

AFCAT 02/2021 Recruitment Syllabus: The Indian Air Force used to conduct the Air Force Common Admission Test (AFCAT) twice every year to select young men to grant Short Service Commission (SSC) and Permanent Commissioned (PC) in the Air Force.

You can become a commissioned officer by opting for the Course through AFCAT, MET Entry, or NCC Special Entry for branches such as Flying or Ground Duty Technical / Non-Technical. However Flying Branch allows you to become a SSC officer. Unmarried young women can also join IAF as SSC officers in a similar way.

**Short Service commission and Permanent Commission**

A Short Service Commission means a limited period career in the Air Force., Permanent Commission Officers will serve till the age of superannuation. Short Service Commission in Flying branch is for 14 years with no further extension.

The primary challenge to become a commissioned officer in IAF is to pass the Common Admission Test. And all that you should focus on right now is how to prepare for the exam. Here you can take advantage of using the syllabus as a useful learning tool to crack the challenges the exam poses. It will help you set the tone for your approach by simplifying the content to cover.

And here is the detailed version of the AFCAT 02/2021 Recruitment Syllabus and EKT syllabus, collected from the original source.
