ACT考試內(nèi)容—數(shù)學(xué)的介紹.

?　　ACT考試內(nèi)容—數(shù)學(xué)的介紹。首先就有同學(xué)咨詢act是什么考試呢?可能大多數(shù)同學(xué)知道sat是美國(guó)高考，同樣act考試也是美國(guó)高考。ACT考試是一個(gè)包含ACT數(shù)學(xué)、英語、閱讀、科學(xué)四個(gè)方面學(xué)習(xí)的多選擇考試。下面小編為您詳細(xì)的介紹一下ACT考試內(nèi)容—數(shù)學(xué)。

　　ACT數(shù)學(xué)考試不是單純的語言考試，而是對(duì)學(xué)生綜合能力的測(cè)試?？荚囍匾晫W(xué)生對(duì)基礎(chǔ)課程的掌握并檢查學(xué)生的學(xué)術(shù)能力，難度貼近高中生。ACT數(shù)學(xué)測(cè)試部分，共六個(gè)方面的內(nèi)容組成了三個(gè)部分的得分：算術(shù)、初級(jí)代數(shù)、中級(jí)代數(shù)、幾何坐標(biāo)、平面幾何、三角形。
