[Prudence]

I agree that there are too many questionable issues for this to be anything but a scam.

However, especially in the sciences, it doesn't surprise me in the slightest that someone with atrocious grammar would be pursuing a master's degree. A friend of mine was a TA while getting her PhD and her lab students were shocked - SHOCKED - that she would mark them down for grammar errors. And she only took points off for the really, really bad ones; the merely crappy emerged unscathed, free from the taint of grammatical improvements. Truly, an alarming number of people are convinced that written communication is simply not worth the investment.
