The test items with higher difficulty coefficients were those calculating and analyzing ones （0.47） with computer and comprehensive analysis ones （0.52）. The items with lower difficulty coefficients were multiple-choice ones （ 0.88 ） and blank-filling ones （ 0.82 ）. Items with lower discrimination coefficients were also blank-fill- ing ones （0.15） and multiple-choice ones （0.19）. The others had discrimination coefficient of over 0.4. The items which lost more scores were calculating and analyzing with computer items （ 36.32 % ）, comprehensive analysis items （ 34.1% ） and noun explanation （23.33 % ）.
