My 2p here!
Even though I am not familiar with Essex, I visited it in September with someone ready for the start of term. I saw loads of passionate student helpers there answering all kinds of questions and giving assistance to new comers. I was also impressed by the beautiful environment and was pretty sure that my friend has made a good choice there. My friend is a very serious student but not really gets hold of the effective learning strategies. He once emailed me that even though he tried hard on the essay, he got a disappointing grade. Working hard may not give him a good grade as there are other factors affecting especially he has a brand new environment to adjust to, feeling home sick and stressed...
I did some research for my friend before he decided to take the offer. According to NSS, 88% of students were satisfied with the university and I didn't see discrepancy in graduate prospects as compared with other unis.
In Hong Kong, Essex is one of the more popular choices for students with an average competence.
If some people are disappointed or unhappy with where they are, they need to cope with it before the situation deteriorates. Others need not disagree because it is personal experience and feeling that we must respect here. During my uni education, I did have ups and downs. I had classmates who seldom showed up for lectures as they were busy with part time jobs. If they treat education like a joke, it is their business.
