What is a good upper second class?

On a similar note, if you have, for example, 63.9, does that always round up to 64 average? what about 63.5? I know that mathematically it has to, but in general academic convention (given that you only get a transcript of individual breakdowns and have to do the average (mean) yourself?)

Depends on the university.

Going by personal experience our results are given to 2 decimal places for the first, second and third years PLUS the final degree average. One of my friends for example was on 68.45 for her final degree classification mark and that's what the transcript says.

so is it actually possible to get into Oxbridge with a 67% ? (given that all other criteria is satisfied)?

Of course. Otherwise they wouldn't state it as their minimum entry requirements -- just as people have been known to get into Oxbridge for undergraduate study with AAB or even ABB at A-Level. The university you attend does, sadly, play a minimal part though (people from a wide range of universities have got into Oxbridge for postgrad), as well as your own motivation and plans for possible research. However, I would have thought that, if you are slightly unsure of your chance of success, Cambridge would be better to apply to than Oxford as they tend to interview postgraduate candidates, whereas Oxford doesn't, (assuming that what is the case in the Classics department -- I've been doing research -- is the same the university over) and thus the interview would perhaps give you chance to show your utter brilliance!

I don't think the undergrad uni would affect your chances at all, surely? They'd appreciate that not all Oxbirgde-worthy students had applied for undergrad, or they might have mistakenly been rejected, or they might just not have developed as much academically until uni.
Countless people have gone to Oxbridge from low-ranking unis. I know someone who went from Liverpool Hope!

a) Your undergrad university really plays hardly any role at all, assuming that the undergraduate university teaches an appropriate syllabus.

b) Cambridge certainly don't interview across the board. They don't in my subject as a rule and neither do Oxford.

c) Apply to both rather than picking one or the other - there's no disadvantage in doing so.

Interesting. Though I would have thought that it plays some role. Maybe not if you go to a university which is reasonably well respected (i.e. a redbrick, Durham, St Andrews etc.) but I find it hard to believe that, considering the many debates we have had on TSR which have strongly concluded that a first from ex-poly X is in no way equal to a first from Oxbridge, they would be considered with equal weight. If they are, however, I'm all in favour of such egalitarianism.
