2、分值差距會比較大，考生在選擇學(xué)校的時候還要比較每個學(xué)校對應(yīng)專業(yè)的分數(shù)就會特別吃力，我們針對此就提供一個信息查詢的平臺，主要由前3到5年某校某專業(yè)的錄取分數(shù)的數(shù)據(jù)，來預(yù)測下一年該專業(yè)的錄取平均分和最低分，使考生在考研復(fù)習(xí)初期以及到志愿填報之前，對每個學(xué)理學(xué)學(xué)校的專業(yè)分值情況有一個大致的了解，從而更合理的安排復(fù)習(xí)以及更優(yōu)地進行志愿的填報。02數(shù) 據(jù) 收 集數(shù)據(jù)收集數(shù)據(jù)收集階段一在此階段把某一專業(yè)的往年考研分數(shù)做一個基本普遍的采集，把每一年所有的分數(shù)都做一個簡單的整理。以下列舉出部分數(shù)據(jù)：2015總分政治外語數(shù)學(xué)專業(yè)備注3986762128141387705412214137965581171393
