Sending Official Test Scores
You must send official test scores to colleges before your application is completed. Most schools allow leeway for the scores arriving after your application has been submitted, but some, such as The University of Michigan, require that everything be in the office by the deadline. Therefore, we recommend sending test scores at least 4 week prior to the deadline.
Below are videos showing how to do it.
