The GMC has a criteria to deem an internship acceptable for Licensure
You must have completed at least 12 months of internship with at least 3 months in medicine and 3 months in Surgery
So the 6 months you did in both ENT and general surgery all counts towards Surgery
So you need an additional 3 months at least in general medicine + 3months any other speciality (ObsGyn, Peds, Psych) to make it 12 months in total.
OR you can choose to do 6months in general medicine
