I scanned my IELTS certificate before sending it out. You need to specify the info on that certificate in your profile. Most importantly, your score in each module. I believe you can put any dates in your profile and if you get an invitation, you can update it later, as long as your IELTS score is not changed (or increased if it was changed ) coz it will change your overall CRS. They will check your IELTS after you are submit an official application not before, so don't worry.
My score wasn't that high, mine is only 453 so I wasn't invited yet, and I am not that optimistic either
