That's fine! It's super easy to learn and you don't need to memorize it, especially if you have your phone nearby, you can just google it. If you won't have a phone nearby, I suggest printing it out or writing it down. Or! You could buy a small book of Catholic prayers, any would absolutely have it in there.
[edit] This is the book of Catholic prayers I carry around with me. It's small, about the size of a wallet.
