Professorlayton1 & Shank2 - don't panic with those scores. I can confirm that my DD had 677 and got 4 interviews. You just need to choose universities which make their choices using your strengths.
675 should be enough to squeak into Sheffield - take a look at the TSR thread last year for Sheffield Medical School and in particular posts from the very lovely Julian, Head of Med Admissions. He has been particularly helpful & Sheffield, unlike some others, are very transparent in their process.
Sheffield have a minimum application cut off but what you need to be is in the top 1000 applicants specifically to Sheffield to gain an interview. Can't remember the cut-off number but it was much lower than the actual number for those who achieved an interview. The score of students being interviewed is a moveable feast but I believe last year was low 670s so you should just make it. Wait for the final results and average score around end of September which we found traditionally fell quite a few points from the interim in August, don't panic yet.
With 11A* Cardiff should be on your list as a definite choice.
Also, from my experience consider Plymouth, Nottingham, Leicester, Southampton, Liverpool, HYMS. I'd avoid Newcastle. Read carefully the criteria for Edinburgh. I can't comment on the London ones as DD wouldn't even consider moving there! Not sure what Shank2 has in the way of grades - tot up the points your DC would get and add.
Bristol was tricky to follow last year & I believe is changing it's criteria for this year - have a good read of TSR & the Med website.
SJ2 is not a problem. Only if you get SJ4 does it prevent some applications.
Make a spreadsheet. Write a stellar personal statement. Ensure you have work experience, volunteering or a part-time job and apply it to the skills you will need to be a doctor.
Spend time (with a notebook & glass of wine) looking at the TSR threads and taking note of the scores & grades applicants quote & who got interviews - suggest November to March if you can't face the whole year! But, remember too there are many who don't go on TSR who got interviews so take it all with a pinch of salt.
Feel free to message me if you have any specific questions. My DD dropped a grade at A Level so lost her place (sob) but she gained 4 offers post interview & her GCSE's were not all A*. It can be done!
Buckle Up though ladies.... it's a bumpy ride.
