IAF Group C study guide
IAF Group C · Work through your exam, one topic at a time.
The IAF Group C examination is the recruitment screening used by the Indian Air Force to fill civilian Group 'C' posts at air force stations and units across the country - roles such as clerk, storekeeper, cook, safaiwala, driver, and various skilled and semi-skilled trades. It is meant for candidates with the minimum educational qualification stated for the particular post, typically matriculation or a higher secondary pass, and it is not a route to becoming an airman or a commissioned officer. The IAF Group C study guide has 6 sections and about 1,967 words.
01General Intelligence and Reasoning: Pattern Rules and Verified Conclusions

The arithmetic is rarely difficult; marks are lost in the setup, not the calculation.

What stays constant is the foundation: knowing your tools and their correct use, measurement and units, workplace and fire safety, properties of materials, and the record-keeping language of your trade.
