In terms of rolling admissions, the sooner the better. You will still be disadvantaged compared to people who took the June or September tests and already have their apps in. Turning in your apps before you get your score will give you the advantage over people who wait for their December score and then fill out and send their applications. Schools can start evaluating your application as soon as your score is in, but if you were to wait they couldn't start until all parts of your application are received (the application itself, Dean's certificates, any signatures if necessary, etc). So really turning them in before your score might only be a small advantage but you will be in line for review before all the other people who are waiting to receive their score.
agree, and you enevr know when there will be a f-up and some schools take weeks to get your app compleate. If anything at least send your app in mid nov so as soon as your score is realsed they have everything ready to go and can review your app from that day on.
