Number of course applicants

I’m trying to find out numbers of applicants for the courses I’m applying for. Is there anywhere I can find this information?

It wont tell you anything meaningful - because what it cant tell you is how many of those people had a realistic chance of an offer. I think it would surprise you how many people do not read entry requirements, and apply without vital subjects, inadequate GCSE grades, or apply with CCC for A* courses etc - and get an immediate rejection. What you really need to know if 'how many people who met the entry requirements in full actually got an offer' - not 'applicants vs. places'.
An example : a Gateway to Medicine course that is only open to Contextual applicants and of those, only with predicted grades below a specific threshold. Yet hundreds of applicants who don't meet these basic requirements still apply every year - hundreds of them. This totally warps the admissions stats and makes it look as though the course is far more competitive than it actually is - ie. if applicants actually met those specific conditions, there were few enough of them that they stood a vey good chance of an interview, far better than the overall stats suggested.
So - be very careful about what you think 'admissions stats' can actually tell you, and don't use them as a guide to where you should apply.
