Not knowing anything about you, this is a very difficult question to answer. But I suggest you ask yourself some questions:
If you go to university, what would you expect to gain from it apart from a qualification at the end?
What would you study? Is this a subject that interests you, that would lead directly to a good job (ie medicine, engineering, etc., etc.)?
Are you prepared to get into debt, or would your parents finance you?
Are you intellectually inclined? Do you enjoy school and learning? Obviously, if you want to study maths and hate learning French at school (just to take an example) you would know that you would be studying the subject that interests you and not the ones that don't. Not everyone can cope, however, with going into further education - do you really, really want to do it? If you feel that you are unlikley to stay the course, then don't bother to start it.
There are many jobs you can get without a degree. It depends entirely on your own interests and abilities. There are plenty of graduates nowadays going into jobs that don't need a degree because the market is saturated with graduates. In a lot of cases going straight into a job after A levels gives you a head start over those that go to university and you don't go heavily into debt with tuition fees. Why not try researching the sort of jobs you could and would like to do?
