Well done on the first. As you have mitigating circumstances, your GCSE/A Levels shouldn’t be a stumbling block to getting through. But you may need to be a little proactive when it comes to speaking to graduate recruitment before you send off your applications. Often it helps if you have the opportunity to explain your situation first, especially as you’re applying to firms where candidates will have achieved much higher grades. If you can meet them at a firm event, then great, or try to give them a call.
