http://www.thecompleteuniversityguide.co.uk/league-tables/rankings Now have a look at this and have a look at the graduate prospects column. The graduate prospects column tells you how likely it is that someone will get a job that needs a degree when they have finished their course.
Look at the top of the column and then look at the bottom. You will see that at the bottom of the column the graduate prospects are not very good. What this means is that many of the students that go to universities at the bottom of this list will not get a job that needs a degree after their university course. They will have to get the same kind of job as they would have done had they not ever gone to university or done an apprenticeship. They won't be able to get a job that needs an apprenticeship because those jobs are not available to people who haven't done the apprenticeship so the job will be one that you could have got straight from school. So they will have the same kind of job that they could have got straight from school but they will have an enormous debt from the university loans. So you see some of these people are doomed because they have been to university mostly because they have been to a not very good university. So going to university isn't the answer to everything you have to go to a university with good graduate prospects.
I don't know why you think you want to go to university. Perhaps you believe the myth that you have to go to university to get a good job. Of course this isn't true. Some of the best jobs require training and apprenticeships not university degrees. If you don't believe me I would suggest that you have a look at how much bricklayers get paid in the UK. Of course it is well known that the London underground tube drivers are some of the highest paid workers in the UK. You do NOT need a degree to drive a tube train. There are also jobs that you can get after an apprenticeship that are better jobs and higher paid than you can get with a university degree.
You seem to think that you HAVE to go to university or you are doomed. You don't seem to understand that some of the most successful people in the UK did not go to university. There are many people running successful companies that started work as apprentices. To be successful at anything you have to be willing to learn and to have an open mind. I know that you have asked this question before and you don't seem to be listening to what people are telling you about university. There are several excellent answers here explaining that university is not for everyone and yet you have asked the same question again. Why? If university is not for you then it isn't for you and you must have a look for something different to do.
