Choir audition advice - choosing a piece to sing from coco

this choir audition is very chill and open to all skill levels and we only have to sing ~1 minute of any song of our choice. I have some experience with being in a choir in high school, but many of the songs I like are very awkward to sing in 1 minute bc of the long intros.

Ive narrowed it down to Remember me from coco. Is this a good choice? its 1 minute and mostly fits my vocal range, i just have to work on the end.

We also have a small section on harmonising + singing scales to find our vocal range. Are there any tips for my last few days of practice? BTW ive never been formally trained before, ive been just watching youtube videos for some years 😔🖐️

btw its in like a few days bc they released audition sign up late😭
