Aspiring Barrister (need to find work experience)

Hi everyone, I’m a year 12 at a state school trying to find legal work experience, preferably shadowing a barrister, but honestly at this point I’ll take anything related to law! I’ve emailed some places but not had much luck and I’m not able to apply to many chambers/firms work experience programmes as I don’t meet PRIME criteria such as being on free school meals or being a young carer. Does anyone have an advice or suggestions of places in London/Surrey I could apply to or contact? I know many people say that you must know someone personally on the inside of law firms, but unfortunately my parents don’t have any connections in the legal world.
