Uni Application

Hello,
I am an international student currently studying A-Levels and wish to study Law and I am worried about the state of my application concerning top Russel group Unis and whether i should apply due to my IGCSE where i got A*AAAAABBCC I am not gonna explain the reason behind them due to embarrassment, but recently i sat my AS exams in Yr 12 which i got all As and am predicted all A*s at A-Level.
I was looking for advice on whether i can still get into Unis such as KCL, LSE and UCL and how much these results IGCSE results will affect my application especially if i get a high LNAT score paired with my A-Levels.
Its not like my school is internationally known for strong IGCSE results but i would like clarity as most posts i see only talk about GCSEs thank you

UCL and KCL don’t place any emphasis on GCSEs. UCL asks for a 6 (B) in English language and maths. So long as your grades meet these requirements, your application will be considered. KCL don’t have any specific GCSE requirements for law. Out of the three listed, LSE is the only university that places a heavy emphasis on GCSEs. A 6 (B) is required in English language or maths, but applicants are expected to have obtained several grades 7-9 (A-A*) at GCSE. You have more grades A-A* than you do B or C. You should be fine to apply, but competition for all of these universities is fierce. They are all oversubscribed London universities that receive many applications from students with stellar grade profiles, who will be rejected every year. Your GCSE grades are good, but you may wish to reconsider applying to all three of these universities. You should also look into applying to universities that don’t consider the LNAT and/or have lower grade requirements (target/safety choices).

Thanks for the advice, I wasn't planning on applying to all three I just wanted to know how they affect my chances to universities of that type.

I would also like to ask how context for IGCSE works, as my school isnt' in the UK and am wondering how highly they would rate it
