BYU Online Courses

So I’m taking an online physics course at BYU and I realized that UCs and most other colleges dont approve that course so do i still have to finish it and send the transcript to colleges or can i just not submit the course? (I’m currently a high school junior)

if i dont finish the course, will i have it on my transcript?

Yes, anytime you take a course at a reputable college, it remains on the transcript.
