You should take general college prep courses, with particular attention to the sciences, especially Biology, though this part isn't absolutely essential.
Essentially no one becomes a herpetologist straight out of high school (you could try, but good luck finding a job). You'll most likely wind up going to college and majoring in biology, which is why I mentioned "general college prep courses."
In college, you'll probably find out that 90% of what your high school biology teacher told you was either oversimplified or outright wrong, which is why the biology emphasis in high school isn't all that essential.
No high school classes, other then your core classes (math, reading, etc.) are required for a profession after high school

The classes you take in Junior High are not a factor. The classes you take in high school do not really affect your ability to become an attorney. And, believe it or not, the classes you take in college don't really matter. Law students can have just about any degree and go to law school. I was an engineer with no thoughts of law school when I got out of college.
