If you are aiming for the Bar, then you should study for a degree, in any academic subject. If the degree is not in law, you would also need to obtain a PGDL, which would take a year. The Bar is an academically demanding profession. It's quite scholarly in many ways. Crikey! I have been writing essays for the last forty years and plan to do the same for another ten years or so.
Opinions vary on the apprenticeship route to becoming a solicitor. One point is that you would miss out on the non-academic parts of the university experience, which many people find life-enhancing.
