I guess the most useful piece of advice was probably that the hardest transition from middle school to high school, is finals. They said that it is the hardest thing to change to, because in middle school, the year just winds down and you don't do much, but in high school, you have to remember everything you learned and then put it on paper.
Well that was the advice my parents gave me. I'm not sure what this accomplishes but, you know, whatever.
