TES stand for Technical Entry Scheme and if you get selected you have a 5 year training and after completing it you will be awarded a officer job in the Indian Army. The eligibility criteria is as follows , you must have passed 10+2 with minimum of 70% in Science with PCM subjects and must be of 16½ years and above 19½ years .

The cutoff will be based on the cutoff percentage decide by the governing organisation. Since you have got 78% I expect you noy to expect any call from the officials because there will be many many candidates who have scored more than that and normally the cut off is about 85%.

Sorry but this is truth.

Thank you.
