There is zero point in discussing the topic of the value of tests such as ESOL and IELTS if most of the participants have no idea what is involved in such exams. Without having an idea of what is involved all you are doing is pontificating about a subject of which you know precious little about. You cannot claim these exams have no value or are scams if you don't know what these exams consist of, or what they text.

It would probably be a good idea to make yourselves aware of the CEFR also, as that is what these exams are measured against.
