How can I learn this piano piece in a short time?

Hi, I'll keep this short and simple. My piano teacher died early this month, and we're having a recital with all of her students to honor her death. I have this piece I'd like to learn for the recital, but I have only a few weeks until the event takes place — I don't know the actual date yet.

My problem is that I was just beginning the Level 2 & 3 piano book ( for later/ slightly experienced beginners ), so this piece is a little challenging for me.

I need some tips on how to learn this fast and efficiently. Thanks in advance.
