I'm thinking of going into law in the future.

I'm in year 12, and I was wondering do I definitely have to apply for a Russell group law course?
Law is competitive and I've heard from others that people struggle to get into work if they haven't gone to a Russell Group uni.
Is this true?
I'm preferably wanting to go to a Russell group as its impressive but it is a lot of work

RG is just 'marketing fluff'. It does not actually mean anything significant in the real world - whatever your school tries to tell you. It certainly cannot tell you if you will like being at that Uni and or enjoy that course more than any other.
Leading Law firms are increasingly recruiting 'Uni blind' - what they are looking for is a good degree grade, 'interesting person' and added-value experiences such as a work-placement or study abroad etc. And btw, many Law grads don't go into Law careers - its a degree that is valuable in a wide range of other career pathways. Go to Open Days, look around, listen to the course presentation, talk to the students doing the campus tours etc and find out what they like about being there. Then do some careful thinking about 5 realistic choices and where you will feel happiest.
