The AFCAT Ground Duty Technical entry requires candidates to clear a two-part objective exam: the standard AFCAT paper and the compulsory Engineering Knowledge Test (EKT). Success hinges on balancing speed in the 100-question main paper with high accuracy in the 50-question technical domain section to secure a competitive merit rank.
What is the Exam?
The Air Force Common Admission Test (AFCAT) is the gateway for Commissioned Officer roles in the Indian Air Force. For technical aspirants, the Ground Duty (Technical) branch is a premier career path involving the maintenance and management of sophisticated aerospace systems, electronics, and mechanical engineering assets. As strategists at Exam Bhai, we emphasize that this is not just an aptitude test; it is a technical evaluation that demands both broad general knowledge and specific engineering mastery. Unlike non-technical entries, technical candidates must qualify for both the main AFCAT paper and the specialized Engineering Knowledge Test (EKT).

Preparation Strategy
Our team at Exam Bhai suggests a dual-track strategy. First, build a strong foundation for the main paper. We advise all aspirants to take the latest AFCAT mock test series on Exam Bhai to identify your weak spots.
- For the Main Paper: Focus on high-weightage topics like Reasoning and English. Spend 60% of your time on these, as they are scoring sections.
- For EKT: Do not rely on rote learning. Use your core engineering textbooks (Class 3-4 subjects) and solve the previous 5 years' papers to understand the depth of questioning.
- General Awareness: Dedicate 30 minutes daily to reading current affairs, focusing specifically on military exercises and IAF-related developments. You can also access curated defence exam study resources on Exam Bhai to streamline your revision.
Cut-Off Trends
Based on historical data provided via the official Indian Air Force recruitment notifications, the cutoff fluctuates based on seat availability and exam difficulty. Generally, Ground Duty (Technical) candidates should aim for a score of 160-170+ out of 300 in the main paper to remain in a safe zone for merit.
- Historical Average: 145–155 marks (Main Paper).
- Recommendation: Target 170+ to neutralize any normalisation effects or difficulty spikes in the paper.
