Which university, Oxford or Cambridge cares more about GCSE grades?

I got majority 8's, one 7 and one 6. I want to apply for law but I don't think my grades are good enough. Which university cares more about them?

Oxford generally has a slightly more formal process in scoring GCSEs for many subjects, but not all weight them equally (most maths and physical science courses at Oxford for example don't put a great deal of weight on GCSEs).

Cambridge is relatively less formal in scoring GCSEs although many applicants do have very good GCSEs anyway.

That said in either case I think your results are probably fine for either uni. Bear in mind both (as far as I'm aware) consider 8 and 9 grades both the same as the old A* grade (so a 9 is not "better" than an 8 as far as they are concerned).

I agree with a lot of it but I believe your last sentence is no longer the case. I remember it being true a few years back but TheOxfordMum updated her Oxford demystified thread to say that the 8/9 being the same is no longer applicable. I also looked at Oxford's official qualifications page: https://www.ox.ac.uk/admissions/undergraduate/courses/admission-requirements/uk-qualifications?wssl=1# and saw that the line where it said 8/9 being the same was removed which makes me believe that it is now considered differently. Unfortunately I was also misled when I completed my GCSE's and even though I was 2 marks off a 9 for a number of subjects I chose not to appeal because of the 8/9 being same rule. (That was a mistake since it's not true anymore)

From looking at their websites, Oxford does give the feeling that GCSES would be a little more taken in to consideration than at Cambridge.
It's interesting because Cambridge generally admits students with slightly higher A Level grades than Oxford. But Oxford interview more.
As I have got older, I respect the Oxford approach much more. The Oxford application process more looks at the overall journey and personality of a student to date. The Cambridge approach just favours the person who crammed for 2 years.

I've heard Cambridge interviews more than Oxford.
