Maybe take some time to properly think about what you want to do in the future. Start by finding what interests you then look for careers you can go into in that area. From there you can look for uni courses or likewise. But your a level choices are great so you still have many options. But don't worry if you don't know exactly what you want to do, you can still go to uni and study a subject you enjoy without knowing what job your going to get from it.
