"If you submit your application before the new system is implemented, you will experience minimal changes. You will not need to update any information, and you will only interact with the new application system during the decision process. If you would like to submit your application before the updates, please submit on or before our October Round deadline on October 12.
If you have already submitted or plan to submit your application after the new system is implemented, any information that you have already entered will be transferred to the new system. Please note that the new application will look different and some questions will be modified. "
