^ Woot, another genetics and psychology fan! ^^ Those are my main interests as well, particularly social psychology and genetic disorders. Chemistry... not so much a fan of that one. X3 It can be fun though, especially if you get to do synthesis or chemical identification labs (where you have an unknown chemical and have to run it through various tests to discover what it is).
I'm not sure what level of chemistry you'd be getting into in high school, but probably the best preparation you could do for it is to learn the abbreviations for chemicals on the periodic table, at least for the more common chemicals. The ones you'll likely be seeing a lot of in chemistry are carbon (C), hydrogen (H), oxygen (O), nitrogen (N), sulfur (S), sodium (Na), chloride (Cl), bromine (Br), iodine (I), magnesium (Mg), potassium (K) and calcium (Ca), as well as some of the metals like silver (Ag), aluminum (Al) and lead (Pb). If you can recognize those by their abbreviations without having to look them up, it'll make understanding chemical structures/formulas a lot easier and faster.
