She's doing her AS ones -- she got her GCSE last year.
Personally I can't wait to see how she's done. Girl must be a genius -- GCSE year, her mother and sister die in a fire, she's sent away to boarding school against her will, severely traumatised (sleep walking etc). Runs away from boarding school to find her father has moved without telling her. Ends up in Walford. Quits boarding school, goes to local school. Finds out father has been having an affair for the last ten years which her mother knew all about, reveals her father only saved her because he thought she was her sister. She quits local school and goes back to boarding school. And the lowest she got was a B.
So really, having to do AS exams after (again) going to about 3 different schools/colleges, finding out her father was a gangster, moving away and living cut off from society, finding out her father ordered Dennis's death, and having to convince her father to turn himself in, losing the one last family member she had left, should really be a piece of cake.
