本文分析北部某私立大學100至104學年五個年度入學學生於大學前兩學年的學業成績，發現三種入學管道的學生，不論是以原始分數、系排名、標準化Z值代表學業表現，均以繁星生最佳，申請生次之，指考生最差，這樣的結論也適用只採計必修科目。繁星生在數理相關科系表現不如在非數理相關科系表現，但仍顯著優於指考生。指考生在課業投入、學習滿意、就學穩定上都較繁星生或申請生差。繁星生在課業投入雖然顯著大於指考生，但這無法解釋他們成績爲什麼優於指考生。高中成績可相當程度解釋繁星生的好成績，但仍無法完全解釋，本文試圖提出原因。

In this paper we analyze first two years' academic performance of students admitted to one northern private university from the years 2011 to 2015. The result shows that academic performance of students from the Multi-stars program is best, whether using grades, ranking in department or z-score as measuring standards for academic performance. This result still holds when using only required courses. Next to students from the Multi-stars program are students from the Application channel, while students from the Joint College Entrance Exam (JCEE) channel are worst in academic performance. The academic performance of students from the Multi-stars program in math and science related departments is worse than their performance in non-math and science departments. Nonetheless their performance is still significantly better than students from the JCEE channel. Academic performance of students from the JCEE channel are worse than students from the Multi-stars channel or Application channel in academic hour inputs, learning satisfaction, and academic status stability. The superior performance of students from the Multi-stars channel over students from the JCEE channel can not be explained by more academic hour inputs. Grades from high-school might be a good reason for their superior academic performance in university. But this factor is not the sole reason for the superiority of the Multi-stars channel students. In this paper, we try to give some other explanations.
