I cant say for any other subject, but this year maths alone has had over 1000 applicants - there are under 200 places available. This year they had to split the undergrads up as there were too many to fit into the largest lecture theatre - which holds 160...
Overall in Exeter they have had more applicants than ever before I believe - they've had so many that they aren't allowing returning students places in Uni accommodation next year, else there wouldn't be enough spaces for the freshers!
