For these students, I will not argue with them face to face, but laugh at them in heart: Since you look down upon those who can do well in the exam, why don't you demonstrate your own abilities?

对于这种人，我不会当面和他争论，我只会在心里嘲笑他：既然你说大学成绩好的同学没有真本事，你又有什么本事？

If you want to know yourself, just look how others do it; if you want to understand others, look into your own heart.

你要认识你自己，就去看别人的举动。要了解别人，就窥看你自己的心。

Look into your own selves and find the sparks of truth that God has put into every heart, and that only you can kindle to a flame.

审视一下你自己，你会发现上帝早就赋予你智慧的火花了，也只有你能点燃智慧的火花。
