Is taking the SAT four times too many (and if so, why is it the case) in the eyes of college admission people?

Hey Mike!

Don’t think of this as added pressure (I know you’re hard at work), but I was wondering how far you were with writing the new SAT math book. Any chance it’ll be out before the PSATs next week?

Thanks!

# M gallons of a p% salt solution must be mixed up with G gallons of a q% salt solution to produce an r% solution.

M gallons of a p% salt solution must be mixed up with G gallons of a q% salt solution to produce an r% solution. Which of the following best describes how to find the value of r? (This question is driving me insane.)

(A) (p + g) / (M + G) = r / 100

(B) (0.01p + 0.01q) / (M + G) = r / 100

(C) 0.01p / M + 0.01q / G = r / 100

(D) (0.01M + 0.01G) / (M + G) = r / 100

(E) (0.01pM + 0.01qG) / (M+G) = r / 100

Hey Mike!

Your PWN the SAT series is ridiculously awesome, especially your math guide. Do you have any future plans of creating a guide for the SAT II math subject tests?
