Is there any chance of me getting into med school with a contextual offer?

Why did your future medics teacher think you're unlikely to get offers?

She basically said I probably won’t be considered as highly as other applicants with higher grades

I suspect there's an element of cobblers to that, as otherwise the contextual and access course schemes would be pointless

@GANFYD might want to chip in here, but I suspect some unis might have a weighting towards stronger grades, but I don't think it would put you out of the running.

It is indeed cobblers.
Unless a med school specifically scores A levels as part of shortlisting (and only 5 do), then all you need to do is meet the minimum requirements - contextual in your case, so anywhere from BBB upwards. You will need to have the UCAT and/or GCSE score needed to be shortlisted (again, often lower for contextual applicants), but A levels just need to tick the relevant box.

Thanks for clarfying regarding the numbers of unis that might take grades into account. I had an inkling it wasnt a huge amount but would not have guessed as few as five

With UCAT and interviews it makes sense that AL are more of a YES/NO tickbox than a lot of courses.

Some do need 2 AstarA (Cambs) as a minimum requirement, others just AAB predicted even without contextual consideration, but very few actually score them as part of shortlisting.
As I say every year, your knowledge of medicine admissions is amazing, given it is not your "area of exterise", so to speak (although you are pretty expert!)

Ha! I think it may just appear that way as when I don't know the answer to something I keep quiet and follow th thread hoping that you answer

I've got a decent amount of experience in UG/PG admissions but med has only been a very small part of it so definitely not in my usual wheelhouse.

I can do med in my sleep and have picked up a bit of UCAS stuff along the way, but other than that, I have no idea whatsoever, so admire you guys spinning so many plates
