I just submitted my app for PSU and also my test scores but I haven’t sent in my transcript yet. I am asking my school to send my transcript on Monday.
Would I be missing the priority deadline, or is PSU okay if my transcript gets in a week late, but my app is submitted ahead of time?
No, unfortunately. PSU doesn’t consider you having met the priority deadline unless you have ALL materials in by the deadline - which is Monday. So you will be in the next wave, which will be more competitive (but certainly not impossible) and instead of being guaranteed a response by January 31st, you will be guaranteed a response by the end of February.
