It's too close to do some hardcore studying, but you should read over the rules for each section and understand them so you don't waste time on reading them.
ENGLISH- don't start reading the passage, start with the questions first. Most of the questions are sentence specific (word replacement/grammar), so make sure you read the whole sentence. WATCH OUT FOR- verb tenses, plural/singular words, and too many words.
MATH- look over some basic trig functions/formulas (sine/cosine/tangent) and memorize the two special right triangles and the relationship of the sides and angles.
WATCH OUT FOR: order of operations. Skip ones that are too hard and come back to them. The last 10 will usually be the hardest, the rest are mixed difficulty.
READING: tests your reading comprehension. Make sure when you answer questions you can find a spot in the passage with the same meaning. WATCH OUT FOR- answers that give more information than was given in the passage. Make sure to watch out for actions/emotions the characters have.
SCIENCE: reading graphs and contrasting ideas. Focus just on the information in the graphs/experiments. Pay attention to the relationships on the x/y parts of the graph. For the contrasting ideas, write simple explanations next to the passage so you don't have to translate from the scientific lingo each time you read it. WATCH OUT FOR: incorrect relationships on answers for graphs, questions that ask you to compare two or more experiments, and remember not to bring in prior in depth knowledge you might have on an experiment. They just want answers that are on the page! Also, you don't have to understand the intense science words. Again, just focus on the graphs and the relationships in each part!
That's all I have! If you want, do a practice test for each sections. You could start with two sections today, and two tomorrow (or tomorrow and Thursday) but DO NOT STUDY ON FRIDAY let your brain have a breather! At this point, whatever will be, will be, so relax! Have a good nights rest and eat breakfast!
Good luck!!
