I submitted my application last september and sent my academic IELTS because I was rushing to make the cap, because at that time we sitll dont know if the cap has been reached or not. Its 2 months now and my DD was encashed, I know somebody who submitted their papers with academic IELTS in august. Actually, before we mailed our papers we had a lengthy discussion with my consultant coz we already knew at that time that they require GT module, but we were rushing hence the decision to submit it was done. If you have time, take the GT because that is what they require, but if none then its your risk to take. I myself dont really know what will happen, now we are just relying on prayers.
Good luck to us.
