Playing to your strengths is wise but I honestly think your daughter has a fair shot at getting an interview at any of them and after all nobody needs 4 offers, just 1! I'd really recommend her narrowing it down now on where she most wants to live for the next 5/6 years, what course style best suits her, anything that particular interests or appeals to her about the uni etc. Do any of the med schools/ hospitals/ top lecturers specialise in something she finds interesting? These are the sort of things she'll need to know anyway when (hopefully) she gets to interview! All of my interviews (2 traditional and 1 MMI back in the day!) asked "Why do you want to come to this university?" and I don't think "because I thought it was my best chance at getting in" would have cut it!
Some things off the top of my head that may or may not be accurate/ helpful:
Manchester is PBL style rather than integrated.
Birmingham doesn't do dissection.
Nottingham is a 5 year course combining both BMedSci and medical degree (rather than taking a year out to intercalate as at other med schools)
Birmingham and Nottingham are campus based.
Leicester is the only one that's not Russell group (although I honestly don't think this means anything it might matter to your daughter!)
Birmingham and Manchester are more "big city" than Nottingham, Newcastle and Leicester
Something like this website
http://www.thecompleteuniversityguide.co.uk/universities/ might give her some ideas to start with.
All the best to your daughter!
P.S. So this is just my personal experience/ opinion-- feel free to ignore! I had similar (if not slightly worse!) stats when I was applying and got an interview (and offer) from Nottingham
When I was applying I had what I felt were disappointing AS results so I decided not to apply to my "dream" universities. I knew that as long as I ended up studying medicine somewhere I'd be happy. In the end I picked 3 sensible choices and one mildly risky one. I ended up getting 3 offers from my sensible ones and a disappointing but not unexpected rejection from my risky one. It wasn't nice at the time but I'm glad I tried. If I had played it safe with all 4 and got 3/4 offers I would have always wondered "what if?". Sometimes it's best not to play it completely safe
(of course this is easy to say 5 years down the line and I do understand where you are coming from. Good luck!)
