Transferable skills are transferable from job to job, and usually refer to "soft skills". In this case, trouble shooting... useful for programming, desktop support, system admin and automechanic.
And I can understand your frustration...
I remember my first year of two at university. I studied hard but my marks did not seem to refelct my efforts. When I moved on to a masters degree, I learned that I was studying wrong. In my case, I was studying on the details without the big picture in mind.
I realized that it was more important for me to look at the big picture, and then work on the details.
In other words, why is this drat old nit-pickey detail worth knowing? Once I related it to the big picture things, I added relavence to what I was studying and things became much, much easier. At least I think that is why things got easier.
It also helped when answering to written questions because I could focus on the important stuff without getting bogged down on the details.
And BTW, sometimes, when trying to justify a detail, I found myself saying - "because they said so" which didn't help me add relavence, but this frame of mind helpded me to accept it and move on.
I suspect that it is sometimes hard to see the bigger picture when mired down with a flood of details. But over time, the details start to make sense as little pieces in a large jig-saw puzzle.
