But one thing is for sure: Your degree focus in English Literature, whether from Colchester Institute or Durham Uni, is of limited value in ESL as well as in public education at genuine, decent schools

Look at the components of a literature course, it has lots of value for teaching ESL, particularly so given the huge amount of writing compositions that are required at CAE and Proficiency levels, not to mention the amount of academic reading from FCE upwards that require detailed analysis of text.

Now, if you've quite finished making yourself look silly on yet another topic you know little about, shall we move on from the foolish notion that an English Literature degree has no value for teaching English?!
