Nowadays young people in colleges and universities are crazy to get all kinds of certificates. For example, teacher certificate, Mandrine certificate, College English certificate. When asked why, the answers differ.Some of them say it could not be wrong to get more certificates to compete with others. Another opinion given by them is to demostrate their ability and possibility. Others say because they are asked to do so by their parents, etc. In my opinion, time is precious and should be used properly. Any certificates not related to my major and futer job could be omitted. Yet the ones that can help me to strengthen my professional abilities will gain my attention. If my major is engineering, a Mandrine certificate will do nothing good to me. But I will put my efforts into engineering certificate. The preparation of getting it is also a journy of study of my own major. That will demostrate my professional ability and help me to get a proper job in the future.
