help! what are some good songs to sing for girls with a lower range?

okay, so i have a solo assessment tomorrow for my certificate 3 in
music and i need to sing up to three songs.
i have left this soooooo last minute and am freaking out.
any help is much appreciated!
i just need a bit of help choosing the songsssss,
so maybe something that is popular so that i don't have to learn a
whole bunch of new lyrics?
i have a low vocal range which i am working on but seeing as this is
so last minute i would like a song in my comfort range.
thankyouuuuuuuuuu in advanced! :)
