It's very common to finish college in three years here. Very few of my classmates are as old as I am. They encourage the math students to take a crack at the doctoral qualifying exam as early as they can. I passed it as soon as I came, and now I can start writing my doctoral dissertation.
在這裡大學三年念完很正常，同學中很少像我這麼老的，數學系尤其鼓勵學生盡早嘗試資格考，我一來就通過考試，現在可以開始寫博士論文。
