Recently, phathumvan university had problem with admission new students. There were a lot of  students that can not pass the test. However , senior  students wanted the university take these students. In my opinion, phathumvan university should not admit low quality students.
First, low quality students may be bad students. Bad students may cause problem to the university. For example, if students fight with students of other  universities, the university have to be responsible for what they did.
Second, phathumvan university may a bad academic reputation. If students are low quality, they are not good at working. Company have to blame the university. It wastes their time.
Third, low quality students may not be able to study. It could waste their time and money. They may be disappointed.
In conclusion, I think that phathumvan university should not admit low quality students.
