In recent years,an increasing number of college students make great efforts to get all kinds of certificates in their spare time.They either aRend training classes outside campus or study on their own to acquire knowledge to pass the exams for those certificates. As for this phenomenon on campus,there are both advantages and disadvantages.On the one hand, in the process of pursuing a certificate in a certain field,students can learn something that they are interested in and that can be applied to their future career.On the other hand,some students spend too much time getting certificates,neglecting their study on campus,which will have a negative effect on their normal college study and life.
