Where a course is offered at both the main Exeter campus and the Penryn campus, one has to add 'C' on one's application to indicate that Penryn is the desired location. It may be, though, that one can 'end up' at Penryn at the results day stage (or even offer stage, of if the requirement for the main site was a bit too aspirational?) if the original offer isn't met, but there are places available on the same course offered in Cornwall. The alternative offer will be flagged up.in Track, though and acceptance / rejection required - there is no danger of applying for Streatham and finding oneself on the way to Penryn come September, without having been personally involved in the process.
DS1 accidentally applying to Penryn campus has been one of my niggling worries. I believe the history course there has a different course number but it hasn’t stopped me checking repeatedly. In the sense of looking their website - I don’t have sight of his actual application, hence, probably, the niggles :-)
