<p>I've been lurking here for quite a while, and it seems almost everyone finishes their SAT sections in only half the time! Meanwhile, I barely finish in my allocated time. I mostly struggle with math, only getting around 650:S in practice tests. I was just wondering if someone has any 'math tips' which help them perform operations/understand equations easier. The more examples = the better</p>
<p>I'll start off:</p>
<p>How to square a binomial easily
(x+1)^2
Square the first term, multiply the two terms together in the middle and double it, and then square the second term
=x^2 + 2x + 1^2</p>
<p>Skip questions I can't get on the first time and come back to them after I finish everything else, which by then I'll have a whole new perspective and can solve the problem.</p>
<p>Also if it's like x^2 - 2xy - y^2 = 34 and (x + y)=5, and it asks for (x-y) then factor the first into (x+y)(x-y)=34 and solve from there.</p>
<p>with math, if there's a question i don't understand, i always skip it and go back later. then i generally have time to stare at it, and it starts to make sense... but that seems like common knowledge, i guess.</p>
<p>If you ever get a shape that is shaded inside another shape, try to rearrange the shaded side so it covers a % of the area of 1 of the figures.</p>
<p>When bubbling in answers, only bubble in after you answer a page of questions- you won't have to keep going from answer sheet to question booklet.</p>
<p>If you're talking about math, I totally feel your pain. Even though I ended up with the 800, I found myself plugging in answer choices into the question because I didn't actually know how to do it. D: Honestly, time isn't your problem if you can at least know you got them all right.</p>
<p>To save time on the CR, I read all the questions before I read the passage. If a question references a certain line(s) in the passage, I underline that portion. As I read, I take note of the underlined areas, pay extra attention, and generally answer the questions as I go.</p>
