What is on the New Jersey STEM exam for high school? What kind of things should I be studying to prepare?

!!!Even if you don’t live in NJ I could still use your help if you have taken this test!!! I am going to be taking this exam in a few months but I have no idea what's going to be on it so I don't know what to study. Has anybody that lives in New Jersey know what is on it? It’s the STEM exam for 8th graders to take before high school.
