That is fantastic, congratulations! You will send that score to every school you apply to. You should not apply test optional anywhere (it doesn’t matter what the past ranges were for the schools, because your score is extremely impressive in the context of your education, school, circumstances, etc…and that is what matters most). Great job.
When you are applying, check to see if the school allows self reporting of the scores in the app (look on their websites), or if they require official scores be sent from ACT. Sending official scores requires paying $18 per school, so save that money by self reporting where possible.
You can also use this resource for self reporting (but still double check websites). Colleges that Allow Self-Reporting of SAT and ACT Scores - Compass Education Group
