Have you looked into completing the associate degree from Pierpont? If you complete this degree and wait for it to be conferred than you would be waived from some of those admissions requirements at UMPI. Having some credits doesn't equal a degree. If you have a degree then they won't requirement the high school transcript. They will still require the college transcripts. They may require the English exam which is a common requirement from colleges for non-native English speakers. The entire program at UMPI is in English and is all written work. They want students to be successful. ESL help isn't really a thing for YourPace as you only have 8 weeks to complete courses not a full semester. YourPace is a significant amount of reading in English and a lot of writing. I have seen several non-native English speakers struggle with the courses. I'm not saying you would, but there's a reason they requirement the exam. It's also not just an UMPI requirement. It's a University of Maine system wide requirement. Many colleges have the same requirement.
ETA: What does this mean?
"took some college courses without earning official credits"
If you took college courses, there is a transcript. Even if it's Ws or Fs, there's a transcript.
