In this study, the students` responses on the items of chemistry Ⅱ in the College Scholastics Ability Test (CAST) implemented for the past 3 years since 1999 was investigated. The number of applicants and mean score of chemistry Ⅱ, average percent correct by contents and inquiry process, and the items with high and/or low percent correct are analysed and discussed. The percentage of applicants for natural science track is reduced each year. However, more than 25% of natural science track applied to chemistry Ⅱ, which ranked second to biology Ⅱ. The mean score of chemistry Ⅱ was increased in 2001 along with those of other subjects. There is no difference in average percent correct either by contents or inquiry process. Students performed generally poor at solving test items relating to `colligative properties of solution` such as `boiling point elevation` or `osmotic pressure`, and very well at solving test items relating to `reaction rates`, Educational implications are discussed.
