My short term and long term memory don't apply to things such as classroom situations, but my short term memory is definitely worse than my long term memory. My mom has been trying to get me to close the kitchen door for 6 months now, and I still leave it open. Why? Because she reminds me everytime, and by the time I get out of the kitchen I've forgotten what she's told me and therefore, do the opposite thing which I am used to. Hell, I even sometimes repeat what I've said because I forget I said it a few moments before.
But, I can remember the childhood memories that I have in great detail, and I can remember most of what my dad told me when I asked him about the solar system 6 years ago. In fact, last year at school we had to write an imaginary story about space, and because I couldn't stuff all my knowledge in the story without it becoming VERY lengthy, I just rephrased what my dad had told me to turn it into a story.
