ABB-BCC?????

HiI know this is going to be in the wrong room but i cant work out how to get to th others:PI was finding out more about doing a degree in Drama at a university in England when i came accross the following entry requirements:We normally require three good A level passes, but the current offer of ABB-BCC may be adjusted according to your background and experience. One of your A Levels should normally be among the following subjects: a foreign language, English, Classical Studies, History, Art or Art History, Music, Theatre Studies. We also welcome applications from mature candidates with alternative qualifications, those with relevant professional experience, and those who wish to defer their entry for a year.Does anyone know what ABB-BBC even is, is it like TEE or something?? So that would mean 3 A levels in your TEE maybe???Im just clutching at straws here.Let me know if you know more.Catherine McStravick
