IF a person has desire and works at it I think they could make it.
That is one thing appitude test do not measure is desire. I have taken several appitude tests to go to work for companies and they tell me that that I do not have what it takes to be an electrician because I donot understand about square pegs and round holes. Well my phone rings in the middle of the night they dont ask if I know about square pegs and round holes or if I have read Shakesspear or if I can do X and Y and Greek math they could care less they just the problem fixed. I was working as a contractor in a large chemical plant and over heard two managers talking about the recent hires not being able to do the jobs and they agreed that all the HR department would hire was people who could pass the appitude test.
