You do not need to send you test scores with your application. When you complete your application there is a place to self report current scores (if one has taken SAT/ACT) and another spot to note that you are planning to take the test in the future. Applicants are then required to send official test scores from SAT/ACT by the deadline for a particular school I would suggest that you register for your test as soon as possible to avoid getting shut-out of your local test center.
