Will I get into medical school at top universities with these gcse grade

There is no such thing as a "top university" for medicine in the UK. All medical schools are accredited by the GMC and considered equal. Furthermore, the NHS is the only provider of graduate medical training posts in the UK, and they follow the GMC guidance that all medical schools are equal - and to ensure that there is no bias in specialty recruitment, they blind recruiters from your medical school. Therefore your medical school cannot directly affect your prospects as a doctor after graduation. "Best" or "top" or "prestigious" or "high ranking" are all meaningless and unhelpful ways to think about medical schools, and in fact focusing on that can make you less likely to get into medical school in the first place by making bad decisions on which medical schools to apply to.

The first and foremost consideration when selecting medical schools to apply to will be what their shortlisting methodologies are vs your profile - and all medical schools have different shortlisting methodologies. If you have excellent GCSEs, then it is best to apply to GCSE heavy medical schools where that is a significant part of the scoring criteria (e.g. Cardiff, Oxford). If you have weaker GCSEs it's best to focus on medical schools which only look at minimum grades in GCSEs and don't score them thereafter (e.g. UCL, Imperial). You also need to consider your performance on the UCAT (and if applicable BMAT) and how heavily those factors are scored.

Your GCSEs will meet the requirements of all medical schools with minimum requirements. You probably aren't competitive for GCSE heavy medical schools though. So just focus on the former.
