Application status question

Yesterday my application status says it was being reviewed and I just checked now and it says how it’s complete and being reviewed? What does this mean? I also sent my SAT scores late because I didn’t realize I had to pay to send them and just thought that me putting the info myself on my application was just the end of it. Instead of received, it says it was waivered. What does that mean??

Waivered likely means they waived the need for them to complete your application review…

Is that a bad thing? My friend said it could work in my favor because it can mean regardless of what I got they can still accept me. I just hope I didn’t mess up my chances

Waivered means there is usually something that you need to complete something, but they are 'waiving" the need for that at this time.
