Wait no one is bragging how they are right and how their sat score raped your mom you get a discusting amount of time for the sat's if you konw what your doing you have more then enough time to plug shit in.

i pretty much agree here, if you have enough time to, absolutely plug and chug the answers, what's the downside? if it catches one mistake and doesn't waste time it's worth it, my advice is to finish the test in whatever fashion you normally would and if you have time go back and check the answers manually

wait until the GREs where you don't have a calculator \o/

(ps the gre math is easier anyway so no worries)

(Since someone has already mentioned the answers for the SAT questions I don't feel like answering it myself, although I used a method that isn't subsitution)

I'm not a practitioner of plug and chug. Using the plug and chug method means you probably don't understand the problem from the root up. If you try to apply this OUTSIDE a multiple choice question, such as in lab work where you may not be given a formula to plug numbers into, you'll be dumbfounded figuring out the formula yourself since you're so used to subsitution. Your ability to think critically is hampered with substitution. Getting accostumed to use false, presumptuous numbers isn't the way to go for finding real solutions. You don't go and jump to a solution in many things that you'll do in college. Though there are shortcuts to pretty much anything, many of them definitely don't involve trial and error.

yeah my english major had a lot of lab work, damn you plug and chug!

On the SAT however, plug and chug (especially after eliminating the impossible answer choices) is much faster then most methods. Regardless if you know the concept or not, doing it will probably get you a higher score, and that's all that matters on the SAT >.<.

Edit: Here's another question I don't get

The eggs in a contain basket are either white or brown. If the ratio of the number of white eggs to the number of brown eggs is 2/3, each of the following could be the number f eggs in the basket EXCEPT

A. 10
B. 12
C. 15
D. 30
E. 60

+ Show Spoiler +

So I put A for obvious reasons, you can't divide 10 evenly with 3 and so you'd had like a third or two thirds of an egg. But in the answer key, it says it's A! Help please

Yeah the wording in the SAT can be a little tricky. When I first read this, I thought 2/3 of the eggs are white, which is what you probably thought as well. Watch out for the word "ratio." I try to think about it as "2:3" rather than "2/3" because I tend to associate the latter with fractions.
