Deleting scores question

So you know how you can delete ACT scores after you take em
Is there even a point if you only send scores from specific dates to colleges?
Also if you delete you score will colleges know if you deleted it or is the record that i even took the test that day deleted too?

There is not really a point if you are only sending specific scores. However, if a school requires you send your entire testing record, then deleting them may be beneficial. Once deleted, colleges will have know way of knowing that you took the tests or that you deleted them.
