“The best” is a subjective measure.
all universities want the brightest students and exam results are the best way of assessing this. They don’t really give two hoots about DofE, musical instruments, gymnastics etc, they want super bright kids to get really high grades in their degrees.
if you look at the top ten in the past five years there are some consistent universities appearing in most rankings.
cambridge and oxford
durham
lse
st andrews
warwick
all may ask for A stars in one or more (possibly in all)
Bath, Lancaster, Loughborough
These are not part of the Russell Group marketing consortium so have to work a bit harder to attract kids. They won’t ask for A stars but will still have a lot of kids applying with A star predictions because they are extremely good top ten universities
Bristol and Kings probably will ask for some A stars in many subjects.
You then have the next batch of consistently excellent universities: Edinburgh, Manchester, UCL etc. they might ask for A stars. They are likely to want at least a couple of As even in the least popular courses
then you have those that typically sit in the middle to high teens. These tend to be well known but not at the top. Such as Leeds, Exeter, Nottingham, Surrey. They’ll ask for As for popular courses but not necessarily A stars.
Then you get those which actually consistently rank fairly low down but because they’re a part of the Russell Group still flock to go there such as Newcastle which is massively popular (party place) but doesn’t rank highly. If they are Russel Group they may still ask for As. This is simply because they can due to the power of being in the group. Others which are in similar ranking positions outside the top 20 are probably only going to be wanting Bs.
This is all generalising massively. There is enormous variation and you have to go online and look at the course requirement for each course at each university. Degrees are not consistent like A levels. Each university runs a different degree course. Every university needs to fill its spaces so sometime you’ll get lucky and get in with lower grades or find unexpected courses in clearing. This year for example there
were medicine places and Durham courses in clearing (although they didn’t drop the grade requirements, it’s just that they had spaces because the kids who thought they would be going there hadn’t got the grades).
And no a 7 doesn’t automatically mean a B. It could end up as an A star.. or a D
