Hi, GDL 2021 student here. I did a lot of wrestling with this myself. I don't work in the legal field yet but here is what I know.To be a solicitor or Barrister you will need the GDL, if you simply want to be employed in Business but have busienss related legal knowledge then a masters will help. there are specific law masters for coportate law it just means you cant be a solicitor/barrister.if you do want to be a law associate of soem kind, like in house council for Apple (lol) then you will need GDL, law ba hons or a law apprenticeshipGDL squishes 3 years of law in one and is intesne (2 years half time)law ba would be 3 at smoother paceand a legal apprenticeship you can work while you learn and there are oppurtunities in all sides of law, it takes longer but its a good balence.I apologise for any spelling msitakes my keyboard is not my friend currently.Some GDLs 'turn into' masters LLM if you add an extra module, normally a disertation. uni's like BPP and south bank in london offer this.I hope this helps.
EDIT: also, from sept 21 the SQE Solicitor qualification exam comes in which is hope to replace training contracts. if your intent is to be a solicitor look that up, as some unis offer SQE prep instead of GDL. The new way is pass SQUE 1&2 and have 2 years legal work EXPERIENCE (not nessesarily a training contract)
