How to remember things? I have a speaking test at school would listening to it work?

I have got a Spanish Speaking exam at school. If I record my revision and listen to it all day, including during my sleep. Will I remember this?

I mainly want to know if I would remember this if I listened to this during my sleep.

I record mine on my iPhone. Listen to it over and over for literally 10 minutes. Come back a few hours later and listen for another 10 minutes. I don't do the whole "Listen in your sleep" thing because I can't sleep with sound. But if you do what I do, you'll be fine. That's how I did my oral exams.

PS. I'm a Spanish major. If you want me to look at it to see if there are any errors I can help you with, post it somewhere on here! Yh, but there are 6 to look at. 6 questions we had to answer.
