Can I get into UCLA with these grades?

Both UCLA and Berkeley are part of the University of California, which is a public university, and the State of California requires the University of California to offer a place to all California students who make a certain score on the SATs/ACT and/or have certain grades. Not everyone gets to go to Berkeley; most people end up with an offer from a lower ranked UC school. But the grades and test scores for out of state and international students are higher than for instate students since the UC system has to take a certain number of California students.

I don't know how they factor in grades for UK students, but it is possible to be considered for admission (they would still look at your extra curricula activities and grades) by test scores alone. To give you an idea, there is a minimum formula which is on their website, http://admission.universityofcalifornia.edu/counselors/freshman/minimum-requirements/examination/

If you qualify by that standard, you likely have a very good chance, since this calculation basically ignores your grades, and if you have A*s that can only help.

You get in with either statewide or local path. They calculate the 9% using SAT/ACT scores and grades. There is a calculator at the second webpage that includes entry for grades and test scores.
But this is only for California residents. If you are international, it's different.

If you want the actual law or political deal that said the top 9% will be offered places you could search online. I think Governor Brown came to some kind of agreement last year or the year before with the Regents about making sure that more California students were being offered places.

It wasn't exactly well known information, but UCal has primarily accepted Cali residents for a long time. The most recent deal itself may be renewing the original agreement, or bumping up the number of acceptance spots. Part of the reason behind this was the State of California providing some sort of financial support to the UC and CSU systems. That led to a major hit in 2010, where there were educational cuts and CSU could only offer 3-4 days of teaching to students per week.
