I like your introduction...It's short but contains everything it should. It's better if you briefly introduce the reasons as to why you believe so, but this is too fine because you may not have all the time at the exam to do it. Also as a tip for the exam, you better write a short intro like this and move on to other paras. Once you finish the essay and if have spare time, you can come back to intro and add the reasons :D
However, your body paras do not contain specific examples : ( That's an issue for you to earn a good score :D
This idea you can actually use for an example in your first body para. There you say that graduates lack necessary skills required by work environments. Communication skill is one of them. : )
In the introduction you stated that you are in agreement with the statement mentioned in the topic.
Yes.... this is a very valid point.
You write well and display a great potential for a real good score for this task.... Pay more attention to the mistakes you did here :D
