so, the letters in AABBCC refers to its corresponding *line*, not each sentence, and the amount of times that letter is repeated is how many takes you do of that line. For this role, it was recommended to submit just 1 take of line 1, so it'd simply just be "A". You don't repeat anything. If 2 takes were recommended for this line (AA), then you'd do a full read of line 1 without any repeats of sentences, and then just do a full read again (preferably with a different interpretation from your other take(s))
unfortunately this audition is invalid for review as it deviates from the proper audition format pretty heavily and makes it hard to judge. however, if you'd like to resubmit your audition for this role with the proper audition format (as I described above), then I'll allow that
