To quote Chris Rock:
I’m a big proponent of focusing on the OP in threads such as these, but sometimes an OP does not know the right questions to ask. In such cases, users will try to discern more information to make better suggestions, which is why questions such as Why, How, How much often come up.
The user has been asked many follow-up questions, but has not returned. But I will ask some more and then limit my future responses to the OP
Does her HS offer Environmental Science as a class! If so,will the HS register her for the test? If not, does she know how to register for the test, and when? Because it’s not like the SAT where you register yourself online; the student needs to find a test center which will register her, and most don’t take outside students.
