Question

graduate diplomas 和 postgraduate diplomas 的区别

直译都是研究生文凭的意思啊。但大学的课程里有这两种能选，不知何意。（把graduate degree解释为毕业生文凭这种山寨解释的就算了）满意的话有追加分。

Answer 1

研究生文迹亩凭（Graduate Diploma ）: 为一年课程 提供相当于本科专业的课程学生。主要是让学士学生毕业生以强化课程的形式学到专业知识与资格，通常修业年限以一年为主。

Postgraduate Diploma课程的设计主要是对已有大学学士学位，而又想习得一技之长的人而开设的。尤其是已有工作经验，但想提高其教育资格者。此种课程通常为期一年，上课的内容不如硕士学位的广泛。
这是我找到的姿槐森解释明洞，感觉其实两者没有太大的区别~~仅供参考吧~
