What is the eligible criteria for the AFCAT exam?

My brother took the Air Force Common Admission Test, popularly known as AFCAT. It is a tough exam to crack, but the good news is, that it's held twice a year. My brother cracked it in the second attempt and became a part of the Flying Branch. There are two other branches in addition to that: Technical Branch and the Non-Technical Branch with groundwork. 

To qualify for this year's AFCAT 2021 exam, you need to know the following:

Educational Qualification: 

• To get into the flying branch, you'd need 60% or above in Physics and Maths in 12th; you should pass the BE/BTech level exam and get 60% or above marks in Section A and Section B tests by the Aeronautical Society of India or Associate Membership of Institution of Engineers (India). 
• For non-technical work, you'd need clear gradation with 60% marks in any field and consecutively qualify the ASI or AMIE exams with 60% as well.

Nationality: Apparently, you can apply only if you're an Indian citizen.

Marital Status: 

• This is an important one because either unmarried candidates below the age of 25 or married candidates above the age of 25 are eligible for application, even during the commencement of the course, they must remain so. 
• If you're divorced or a widow, you'll be out of the race.

Mental and Physical Fitness: 

• To join IAF you must be 162.5 cm. For the non-technical branch, male candidates should be at least 157.5 cm tall, and female candidates should be at least 152 cm tall. 
• If you're from the North East, then a 5cm relaxation will be provided. 
• The weight will have to be in proportion to your height and mental wellness is an important aspect of the scrutiny as well.

Age Limit: 

• It depends on the branch and method of entry, the flying branch takes in students between the ages of 20-25. 
• Candidates with a commercial license issued by the DGCA are given a relaxation. For non-technical posts candidates should be between 20-26. 
• The upper age limit for flying branch aspirants is 26 years, there is no age relaxation for those interested in non-technical posts.

You won't be allowed to stay with your family during the training period, so keep that in mind. You must keep a check on the notifications which might vary from year to year, also the Testbook is a place for mock tests and resources. So you could use it for studying.
