Law is the better bet, you can still work in business but the revers is not true.
Good luck, Steve.
Law is always going to be the winner. Going forward people who get on in business are mostly full of sh1t relying on the latest buzzwords and eventually trip up. With a pukka law degree you would be qualified to join a company at board level as company secretary.
Don't ask what I'd would do, you're the one who will be sitting the course, not me.
Think about whether you could realistically get the grades for each course, what one would lead into a job you'd be interested in and what one you think you'd enjoy the most etc.
