Hey,
This is a really common question - and i'd be lying if I said that a LOT of people on biomed are rejected medics, and actually I know a fair few people who are vying for post graduate medicine after this degree.
My background is that I originally applied for medicine, but towards the end of the application cycle when offers / rejections were going to be given out I really regretted applying for A100 for various reasons. I got my backup 5th choice at Bristol very early on, and then went on to get 3 medicine rejections (as you do haha), and was awaiting to hear back from BSMS. It was by this point that i'd already seriously started to regret applying for medicine entirely, and was close to picking Bristol cellular molecular med (bristols fancy name for biomed essentially) regardless of BSMS getting back to me.
Anyway, I was borderline interview from BSMS but didn't get one, and they gave me the chance to swap to another lifesci degree at Sussex. (Anything from neuroscience to biochem / ecology / biomed you name it). I actually preferred sussex uni to bristol when applying, so I jumped at the chance, especially when seeing what the Biomed course entailed. Then I never looked back.
So that was what seems an eternity ago now, and honestly looking back it was the best thing that could have happened. I've never in the entirety of my degree wished to be a med student, because I found what I was doing on biomed interested me way more. In hindsight, when applying for courses I should have picked biomed over medicine, so for me it worked out for the best in the end. (Just a darn pain in the arse to think of all that UKCAT / work experience stress was for nothing
)
NOW - whilst thats my story -- there are a lot of people on the course who deep down do want to be med students, however i've found its less than the amount thats touted on these forums. Most people I know and have spoken to are more keen to go into research / consultancy / pharma than those who are interested in going for post graduate med at this point in time. Whats interesting is that most people who started out with the sole intention of doing post grad med (which in Y1 was a lot more people) have actually found they're more interested in other subjects and have ditched the idea entirely - which is especially more viable nowadays given the dreadful ****ing state the NHS is in. I have a lot of friends on medicine, (as I have friends who transferred after Y1), and to say they're regretting their choice is a lil bit of an understatement. (One GP told my mate doing placement, get to NZ as soon as you can, the NHS is done for). Which is just what you wanna hear knowing you're getting in that prof haha.
I guess that answered your Q? Its easy to get wrapped up in med applications, and honestly I can't stress enough to people looking, look about at other allied courses - you might end up surprising yourself.
TL;DR - Med reject but dont want to be a med student because turns out I like biomed more.
