Back when I was a T.A. in physics I'd be rich if I had a nickel for every time somebody told me "I understand the concepts but I just can't do the problem" and then, when I worked with them to debug their answer, found that they really got the concepts backwards.

One big theme I see is that people want something emotionally out of physics that it just can't give and if you are misaligned on these you are going to accomplish nothing even if you can do the math:

Even to the extent of giving hints, you create an unhealthy learning environment. “You have the potential of being smarter (higher IQ), so no help for you. Go figure it out yourself because we’re fairly sure you can.” vs “Oh you poor dumb fool. You’re obviously never going to be capable of supporting yourself so we’ll make sure to carry you there with these extra handicaps. Don’t worry about trying to work harder, we don’t think you can.”

Over dramatized but you get the point. One group is mad about the support the other gets. And that other group loses incentive to really try for things since the solutions, or at least the paths to them, are always sitting there waiting.
