What is some usable and practical high school advice?

-My friends and I are going to high school next school year, and like everyone is, we're nervous. We really need some advice ranging from what study habits we should develop, what to do during class, etc. to what age is appropriate to date and how to politely turn down people, etc.

Any advice would be greatly appreciated.I won't tell you the whole "go out for different stuff, try out new things, etc." because you're probably going to get hundreds of answers like that.



My greatest advice is to get to know your teachers. They will be the ones writing you recommendation letters or being references for jobs in the future. Show a teacher that you are hard working and willing to learn and generally (not always) the teacher will come to respect you and want to help you in whatever you do. Plus, it helps if you need to complain about another teacher.
