  7日的新SAT数学部分整体难度:新SAT数学部分真考的形式和OG完全一致,内容和难度上也与OG保持着高度的统一。

  考察知识范围方面, 新SAT OG在统计学环节大大加强,新加入了标准差, 抽样实验思想等考察内容, 并提高了对数据分析和回归关系的考察难度。
 
  题型和阅读表达方面,真考和OG同样体现出了题干变长和应用题比例升高的趋势。但对于准备过SAT阅读程度的考生而言, 阅读速度和理解并不会成为太大的障碍。相比Princeton等参考书的模拟题,真考的阅读难度并不足以为惧。
 
  本次数学考了Linear function,quadratic  function, the discriminant of quadratic function, long division, exponential growth, the standard equation of circle, similar triangle, Pythagorean theorem
 
  下面还原部分的新SAT数学真题,大家可以来回忆和研究一下:
 
  1. Function
  (1) Given the relation of the distance and the time, find the average speed.
  (2) Given two functions f(x) ,g(x), w(x)=f(x)+g(x), and a input-output table, find the w(x)=x.
     
  2. Linear function
  (1) Interpret the slope and intercepts.
  (2)Solve the linear equation
   
  3. Quadratic function
  (1) Determine the number of solutions by using the discriminant
  (2)The shape of the graph of a quadratic function (open upward or open downward; the vertex)
  (3) Find a model to best fit the scatterplot.
  (4)The addition of complex number
   
  4. Rational function
  Change the the rational function into the mixed fraction by using the long division.
   
  5. Mixture
  Two bottles of solution with different concentration are mixed. Given the concentration of two bottles of solution, the concentration of the mixed solution, and the volume of one kind of solution, find the volume of the other kind of solution.
   
  6. Statistics
  (1) There are two rows of numbers but one is missing. Given the mean of them, find the missing value.
  (2)Given the percentage of students, teachers and parents in a school and the number of administrators, find the difference of teachers and parents. (Find the total number and then times the difference of percentage)
