UCL-HKU law degree

I am considering applying for the HKU-UCL dual degree to enroll in 2026, but I have a few questions:
1. For those who have already applied, do u think it's easier to apply from HKU as a student in the UK or will it be the same competition level as applying via UCAS
2. If I apply for dual degree from UCL or HKU can I still apply for both of the unis regular LLB
3. For those who did the HKU LLB, would u recommend doing my entire course uni in a whole new country as someone who has lived in the UK for basically my whole life. Or do u think doing a year abroad is better/ just going to a uni in the UK
4. I am considering doing a law related EPQ, however ik it may not be very useful when applying for Russell group unis but do u think it may give me an advantage when applying to HKU
Thank you so much (ik it's a lot 😭)
