EKT is an Engineering Knowledge Test conducted by the Indian Airforce, for the selection of officers. EKT is held twice a year, after AFCAT examination. EKT is for 45 minutes. Only mentioned engineering streams aspirants can opt. for this examination. If aspirant is above cutoff marks decided by the Airforce, he get's a call for SSB at AFSB.
Here, we have solved a previous year EKT question paper for you, to make you familiarise with the pattern. However, the level of questions, is increasing in every test. So, in-depth concept clearance is required for EKT examination.
