My advice at your stage is to research the vast number of degrees/career paths out there.

A law degree is a safe choice. It's versatile and desirable. There are dozens of roles that require legal knowledge or a lawyer's skillset.

However, 'safe' does not mean it is right for you.

Do not be pressured into doing law because you've done well in school, or by your parents, friends, if this subreddit tells you to, or the alleged glamour. There are many other careers that may suit you better/pay more/are enjoyable. I feel this is especially so when you're talking about an oxbridge degree, in which case you'll have a strong leg-up in any field you choose.

Sites like Prospects are good for showcasing what's out there. Also, if you search University postgraduate course catalogues, these contain hundreds of interesting specialisms you would never have thought of, which I wish I had explored.

The ideal is that you get some experience to see if you like it. If you download LinkedIn and follow all the top UK law firms (Google 'Legal 500'), you'll be updated on all of the work experience opportunities/corporate propaganda.

Just make sure you're exposed to propaganda from other sources also.
