Yes, a 2.1 is definitely good enough to be accepted, so I wouldn't worry about that. My go to advice for any non-law students is that it is important to highlight the transferable skills that you have learnt in your degree (of which there will be many). For example your commercial awareness and business acumen from your business degree. More widely, you need to demonstrate a genuine interest in law and the work that a firm like HSF do, so if you already have that then you are in a great position.
All the best,
Thank you for your feedback!
