The site appears to be legit with real work offers (makes a pleasant change), but it is insulting too. As with most of the internet these days, it appears to be overrun with Asians, who have no idea how to write. Yet feel able to tell you, you can't.
I have to take exams to prove I can write English, God damn it! I've been writing it since before these Asians were born. How do I know the site is run by Asians?
The grammar in the exams is severely awkward to read, you spend almost as much time deciphering the words, as doing the exam.
Here is a laugh!
I failed the Grade 1 UK English, but passed the Grade 2 US English exam
I was contacted by a Pakistani who wanted me to write an article about housing for seniors in Vancouver, after I told him I had only been to Alberta.
