Hi Alfie! Congratulations on your results, those are really strong grades! A-Level requirements for firms are not typically higher than AAB, and this notwithstanding, all firms that have A-Level requirements will always take contextual information into account when assessing your application. There are also many firms (
Freshfields and
Baker McKenzie to name a few) that do not have minimum A-Level requirements, and this seems to be a growing trend within the industry.
In terms of grade requirements, firms are often more interested in your degree grade at university. Typically they look for a 2:1 (although if mitigating circumstances exist, these will of course be taken into account). This is definitely something to bear in mind once you start your degree. Best of luck with everything!
