Anything can be true if you come at it from the right angle.
For example,
I am familiar with logic circuits, LCLG, circuit repair, etc...
True in that I have recieved training in these areas. True in that I once understood the math involved well enough to troubleshoot quickly. True in that I know how to do the steps nesiccary to repair a circuit card.

However...
False in that I could pull a video card out of my computer, hit it with a multi-meter, determine what isn't working and replace that part. Even though my job description from my previous job implies that this should be true.
