It is a useless operation and should be closed down immediately by the authorities, and EF needs to be banned from China altogether!

Absolutely correct, Turnoi! And further to what you have stated, I should add that their foreign teachers need to take a close look at themselves! They are aiding and abetting this scam by assisting the perpretators of it! What's more, real teachers don't tamper with students' grades. Disgusting and disgraceful!
