Coronation Street fans are convinced Catherine Tate had a guest role on the soap - but it was a case of mistaken identity.
The ITV soap aired scenes tonight, as Summer Spellman and Aadi Alahan took their exam. Summer has been nervous about her exam - and didn't have to take it after her recent health scare, but she felt it was best to go and do it in person.
Aadi had made some revision notes for Summer but in a panic, worried she wouldn't be able to remember everything, she snuck the notes into her pencil case alongside her insulin and tried to use them.
