Common girl, I was not talking French or Latin
You can update it as many times as you want before the ITA is issued.
the date you originally created/submitted your profile is what matters for the ITA
my own example.... I created the EE profile on 16 Feb and submitted it on 20 Feb, CRS score 441. Made a change with a revised language score and submitted which took my points even higher on 2nd March, CRS score becomes 459
My profile says: Date application received: February 20, 2018(EE application original submit date).
It happens all the time, while going through the EE process we all stop thinking rationally. Relax...
btw how did you manage to score 998 ?
