Math old JJ: #8 (eclipse area), #11 (ccircle), #15, #16, #30, #35, #39, #53 (variant: the questions shows the result is 350 for all the digits of number 10^n - 52, show n=?), #63,
One math question: ask if x > x2? 1). x > 0. 2), x > 1 f(x) = x - x2 = x(x-1) > 0 ==> x > 1 or 0 < x < 1 therefore, if x > 1, it is clearly that f(x) > 0, so the answer is B.
Another math question: which number is most closest to 1/2? choices are: 4/7, 5/9, 6/11, 6/13, 9/16 solution: calculate the result of each number substract 1/2, and the result is obvious, should be the 6/13 one (that one results in 1/26), which is the smallest among all the substrated results.
another one is similar to #93, but the question is: seniors only (20), chemistry only (xx), there is a condition says the total chemistry students are something, from which we can know that the common area of (senior and chemistry) is 4, ask: what percenatge of seniors are in chemistry? 4/24 = 16.67%
