How to get a hire acceptance rate at uni?

Other than good grades, what else can I do to stand out?

For those who have already gained admission to a good university, what do you think contributed to your acceptance?

I'm considering pursuing law and am very interested in the double degree program at UCL Law and UHK.

I've spoken to some individuals here who have been admitted to top Russell Group universities, and they have taken 4-5 A-levels, as well as the EPQ, etc.

As for me, I am currently studying 3 A-levels and have completed a 3-week internship at a law firm. While this may not be considered extraordinary, the program I aspire to join is highly competitive. I'm uncertain about what else I should do to improve my chances.
