grannytomine,, the previous generation of actors often got away with not going to drama school at all, not even at HE level
these days, it is far more difficult as agents and casting directors expect formal training before they will even consider you (or significant experience, which you won't get unless you already have the training)- basically, the industry is getting more and more impatient; they don't want to spend money teaching someone the ropes when there are others who already know them
it is still possible to attend an ordinary school and only audition for drama school after Sixth Form but:
- to have a chance to get into HE drama school you need not just raw talent but also very good auditioning skills - which is something most ordinary schools don't teach
*even if you don't do any extras, the actual process of auditioning is far more expensive than your ordinary UCAS university application: you have to pay extra audition fees and travel to the school not once but for repeated rounds of audition
this makes acting an increasingly difficult goal to achieve for poorer students
