			i cant speak for operators, but for pipefitters, the aptitude test was a joke.  its just a formality.  the hard part of getting in was knowing someone/being related to someone.  operators might be different in that you may not have to be related/get sponsored.  i do know, however, there are different levels of operators.  probably dictated by either aptitude, skill, but definitely experience.  be prepared for upper high school level math and reading comprehension.
