秀才、进士、举人、甲第那些单词有什么区别?好像它们都是指在中国古代科举制度下成绩特高的考生。准确的区别是什么?哪些至今还在使用?
(麻烦大家帮忙改正中文错误!)
What is the difference between 秀才, 进士, 举人, and 甲第? They all seem to refer to students who did particularly well under the ancient Chinese imperial examination system. What's the precise difference? Which ones are still used today?
