Thank you for your question. Most medical schools will require a 6/B in English – you can see the GCSE entry requirements for each med school here: https://www.themedicportal.com/application-guide/choosing-a-medical-school/gcse-requirements-for-medicine/
However if there are specific medical schools you’re interested in we’d recommend looking at the medical schools’ websites themselves to check as GCSE entry requirements are particularly subject to change at the moment with the numerical/alphabetical grades.
Hope this helps! 🙂
