This is exactly what I would like to confirm. The slightly challenged cadets are removed and there is no question of semester repeating as mentioned by Malirm. Cadets are removed at ground school stage and others at core flying. Three cadets from my batch out of 9 have been removed and we are only at MCC stage at Alpha and I cant sleep at night because it could my turn next at MCC stage. The batch of 9 will be reduced to 3 by the time we reach line training. The entrance to Alpha is made so easy that even a sixth standard primary school child can get in. Then they fill up their seats by giving false figures like 100% success.
