One test was when I was in high school, and I had just started dabbling with my first guitar for about six months. The other was quite recent, and my score was 20 points higher than the one in high school. …. or if I have just got better at taking Tests?
IQ tests basically show how good you are at doing IQ tests.
At best you can say that they are measuring contextual intelligence. The context being Western "middle class ecology" - i.e. how you function in a 1st world developed economy.
Of course that is an internet armchair opinion.
I assume that if you read up on the stuff there are no doubt dozens (probably 100's) of different kinds of tests which test for specific skills and may be quite reliable in their own contexts. You can improve your score in any test simply by repeating it often enough - doing tests is in itself a learning exercise.
My sister had one professor in the university who came in any day one and handed the students a list of 20-30 questions (essay type exams - not multiple choice) and said the list included all questions that would appear in their final exam. Of course the list in fact covered every topic in the course.
