im taking my sat on october 1 and im so scared because i look at some of these questions and i don't remember almost nay of it.. and i need to get at least a 1270 on it to get my scholarship... what is a good studying method?

[patrickJMT]

@nicole2cool1 take practice tests. take some more practice tests. study those sections that give you difficulty. do some more problems. take some more practice tests. and for the love of god, do not wait until the week before the exam before you start doing this. hopefully you started studying over the summer break if it is so important for you.

just a comment...wouldnt it have been easier to just multiply the 5*2 for the guitarists instead of going into facotrials and such?

[xFiasco33]

@r0met0talwar This just happened to be a coincidence. 5 C 2 = 10, but for example, 6 C 2 = 15, which is not equal to 6*2 = 12. If you think about it has 5*2, then unless you get this same example on a test, you will most likely get the answer wrong.

@ActorFlautista NOin this case it just coincide but u cant multiply 5 time 2 u have to use the combination formula. for example 8 C 2 is not equal to 16, the real answer is 28

[chinotovar]

@boy29girl he said it. take the difference (5 - 2 = 3) another example is 8 C 3 (8 - 3 = 5)

[boy29girl]

help!!!! i can't figure out where did you get 3(factorial)

[purpleleach1]

Umm.. wow I can't count, 800+600+600 is 2000.

[purpleleach1]

@nicole2cool1 800 math, 600 critical reading, 600 writing in other words is my goal. That would be 1400 if you count math & critical reading.

@nicole2cool1 HI NICOLE! I'm taking the SAT the same day as you are! My goal is a little bit higher than yours and I'll tell you I'm just as scared! Lol. My aim is pretty much a 2200 on the SAT and a 800 on the SAT math. This is pretty much a requirement to getting into MIT (not really but statistically).

[nicole2cool1]

@patrickJMT yeah im studying a lot, its just my counseler thought it was good to just sign me up a month before the exam and not knowing till the other day, she wants to see how i do without prepclasses, but at the same time i really want to pass something lol
