  新SAT數學部分整體難度:新SAT考試數學部分真考的形式和OG完全一致,內容和難度上也與OG保持著高度的統一。

  考察知識范圍方面, 新SAT OG在統計學環節大大加強,新加入了標準差, 抽樣實驗思想等考察內容, 并提高了對數據分析和回歸關系的考察難度。

  題型和閱讀表達方面,真考和OG同樣體現出了題干變長和應用題比例升高的趨勢。但對于準備過SAT閱讀程度的考生而言, 閱讀速度和理解并不會成為太大的障礙。相比Princeton等參考書的模擬題,真考的閱讀難度并不足以為懼。

  本次數學考了Linear function,quadratic function, the discriminant of quadratic function, long division, exponential growth, the standard equation of circle, similar triangle, Pythagorean theorem

  下面還原部分的新SAT數學真題,大家可以來回憶和研究一下:

  1. 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

  2. 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.

  3. Linear function

  (1) Interpret the slope and intercepts.

  (2)Solve the linear equation

  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)

  以上就是小編為大家帶來的關于SAT考試的總結,希望對大家有所幫助。更多SAT考試成績查詢、SAT閱讀技巧等問題可以咨詢我們。
