First of all, the hardest parts are gonna be the Math and the Reading sections. The math, 25 questions you are allowed to use the calculator (and you will have to for these questions) and 25 without a calculator. Learn how to use the calculator if you don't already know.
The reading you're going to have to interpret poetry. That's some hard shit when it's multiple choice and there's only 1 right answer. So good luck.
The essay they will give you a random topic...mine was "talk about a special moment in your life". That should be easy if you have any writing talent.
The science is pretty much reading comprehension.
And social studies, you have to look at a lot of graphs and determine what they mean. It's pretty easy.
Overall you have to get 410 out of 800 to pass, which islike 52%. But even if you get 100% on all of them but then get a 50% on one of them you don't pass. Fortunately, You only have to retake the part you didn't pass, and that will only cost you 15 dollars, but you got to wait 6 months to take it again. I reccomend you study hard tonight, go to bed at a reasonable hour, wake up early and eat good. You'll prolly be fine. Good luck.
