calm down seriosly
Hey stop being mean!!!!! It's true she suppose to help, not to give answers. Also she is not going to be there when you take the real test.... What if you're youre teacher asks you questions about this.... Learn little guy..
The reason she is not giving answers is because this is a test the answers she gives is for quizzes your not allowed to have help on tests don't be upset that's why you are suppose to study before you take a test I go to a school called Texas Connections Academy. If you really need help with test take notes if your able to no need to be upset calling Ms. Sue names she has the right not to help on tests because a test shows what you learned or what you need more help understanding.
I'm crying right now... BOO HOO!
if you posted one question and showed that you were doing some research on it, you probably would get a response
You put the whole Science Test from your online school stop that is called cheating you can get kicked out of school for that!!
