Submitting official scores for SAT/ACT

Do I have to submit official scores for the SAT now? On the application portal, it’s showing an X for official scores, but most other schools allow me to submit this once I get accepted. Can I wait until after I find out before sending my official scores? No point in wasting money if I end up going somewhere else.

According to that website, it says they’ll review applications without an official score if it’s a financial hardship. I can afford to send scores in, but it’d be better if I could wait until I find out before sending scores.

Send them now. Since you’re not in a financial hardship, send them.
