I have not. It sounds like your only getting part of someones story. If you pass api then you passed. I dont think that the wing is going to attrite someone before they even start training. Now, if a person starts ground school and tanks the first couple of tests or bombs his CPT's, then they may look back and see if he has a problem. So, I would be willing to bet that you arent getting the whole story if someone told you that. I know a guy that barely made it through ocs (academically), and the same at API. He's barely passed the ground school here and even tanked a cpt and got a ready room down. He is still in training. So.....If looking at his situation compared to the story you have given, it just dosent jive.
