I actually believe that IQ can change during a person's life, in either direction. I genuinely believe I am smarter/better at analyzing/better with my memory etc. than I was a few years ago. I'm not sure if this is generally accepted, but experience tells me it's true.
In general the IQ stays about the same across the lifespan. However, it is of course possible to improve your memory or your ability to analyze things. After all, that's a major part of what people learn in school, especially college- more sophisticated ways of thinking about and analyzing information. IQ tests take this into account. After all, my skills as a five year old were much different from what they were when I was fifteen, but there was only a difference of 5 IQ points between the two testing sessions 10 years apart. Although your ability to work with abstract information is a part of most IQ tests, they also tend to examine things like speed of processing and working memory, which aren't likely to change. Do you have any evidence that your IQ actually has changed (significantly, not like just ten points or so), or do you just feel like you can analyze things better? The latter is certainly possible, even probable, but I'd need more evidence before I'd believe the former.
