F7 (undergraduate) or 7F (postgraduate) is a formal academic exclusion. It means you have not met your faculty's progress requirements and have been excluded from your programme. The only way to challenge it is to submit an appeal to your faculty within its deadline. An F7 is different from an E1 or E2 warning, which only tells you that you are at risk.
