What is normally self-reported are AP’s, in which case it would be a waste to spend the money. Schools don’t expect you to end official reports until you matriculate. If you are referring to SAT2’s, you can send those along with your SAT for the same fee. You would have to pay separate if you are sending ACT scores and not SAT scores. I have not come across schools allowing you an option to self report SAT or ACT scores, but there could be cases or it may be the case for international students for that school. In any event, if the school allows it, save the money.
