先來看看ETS官方對于GRE考試中語文數學部分的評分是如何進行的:TheVerbalReasoningandQuantitativeReasoningmeasuresaresection-leveladaptive.Thismeansthecomputerselectsthesecondoperationalsectionofameasurebasedonyourperformanceonthefirstsection.Withineachsection,allquestionscontributeequallytothefinalscore.Foreachofthetwomeasures,arawscoreiscomputed.Therawscoreisthenumberofquestionsyouansweredcorrectly.Therawscoreisconvertedtoascaledscorethroughaprocessknownasequating.Theequatingprocessaccountsforminorvariationsindifficultyamongthedifferenttesteditionsaswellasthedifferencesindifficultyintroducedbythesection-leveladaptation.Thusagivenscaledscoreforaparticularmeasurereflectsthesamelevelofperformanceregardlessofwhichsecondsectionwasselectedandwhenthetestwastaken.上述這段內容引用自ETS官網的GRE頻道。通過這段內容介紹要為考生糾正的一個認識是,GRE考試的語文和數學部分并非1道題目1分。雖然考試題目數量和分數區(qū)間正好對應,分別是40題和40分,但這并不代表這每道題目就是1分。實際上GRE考試的語文和數學分成2個SECTION(有加試的部分還會多一個SECTION),而第二個SECTION的難度是會根據第一個SECTION考生的解題情況來進行調整的,也就是所謂的section-leveladaptive。考生如果第一個SECTION表現(xiàn)較好正確率高,那么第二個SECTION的難度就會上升,當然大家的得分也會會因此提高,或者說進入高分區(qū)。之后哪怕在第二個SECTION中錯題數量較多,得分方面仍然會有一定優(yōu)勢。GRE培訓:...
