What is the Exam?

The Air Force Common Admission Test (AFCAT) is a national-level competitive examination conducted biannually by the Indian Air Force (IAF). It serves as the gateway for commissioning officers into the Flying, Ground Duty (Technical), and Ground Duty (Non-Technical) branches. As experts at Exam Bhai, we emphasize that this exam is designed to test not just your knowledge, but your 'Officer Like Qualities' (OLQs), including speed, accuracy, and logical decision-making under pressure.

Preparation Strategy

To master numerical ability, adopt a layered study plan. We at Exam Bhai suggest the following:

  1. Foundational Phase: Start with R.S. Aggarwal's Quantitative Aptitude. Focus on understanding formulas rather than rote memorization.
  2. Practice Phase: Consistently use the Disha Publication’s Chapter-wise Solved Papers to understand the question structure. You should also solve daily speed-math challenges on Exam Bhai to build your mental calculation speed.
  3. Revision Phase: Create a formula sheet for quick reference. Dedicate at least 45 minutes daily to solving 15–20 questions across mixed topics.
  4. Mock Test Phase: As the exam approaches, simulate the 2-hour exam environment. Attempt full-length mock tests on Exam Bhai to refine your time management skills.

As per recent historical data (referenced from official IAF result archives), the cut-off generally fluctuates between 120 and 155 marks out of 300. Candidates are advised to monitor the official IAF portal for real-time updates regarding specific session results.
