BBB Unis For Science-Based Degrees

Which Russel Group universities can I apply to for science-based courses (eg biomed, biochem, pharmacy, pharmacology) with BBB predicted grades?

Use the course search on UCAS and then add UCAS points filter to narrow down courses with your predicted grades:

You'll be excluding a lot of good unis (Bath, Lancaster, Loughborough, etc.) if you just focus your search on Russell Group unis.

The usual advice for your 5 choices is -
1 or 2 choices just above your predicted grades - 1 grade and not in a avital subject.
2 or 3 at your predicted grades
At least 1 choice well below your predicted grades as your potential Insurance.
So, with BBB predicted grades, you could risk 1 or 2 choices at ABB.
Just be prepared for No, and make sure your other choices are courses/Unis you still actually want.
There is nothing magical about RG Unis - it doesn't mean 'better course' or that you will automatically be happier there.
For Pharmacy, its a GPhC accredited course and all courses qualify you as 'a Pharmacist' -and the NHS wont care where you trained and neither will your future patients. For other subjects, look for courses tat include placements/work experience etc - these add to your graduate CV and immediate job chances.
