Many thanks again.

Could you advice on below, please:
"Applicants should not delay in providing their evidence of English language ability. The department will not delay finalising applications where English language test results have not been provided at time of application. Applicants will have 28 days from the date of application to provide their English language results if they did not provide them at time of application. At this point in time, if evidence has not been provided the application will be refused."
Is it so strict in reality?
We're appliying now with IELTS 6th for each module and planning next IELTS exam in 3 months time to get better results. Are they really able to process our application in 28 days time and made a decision based on the IELTS results we provided at the application time?
