Type it and copy and paste it into a word to speech generator (just google 'words to speech') and listen to it over and over whilst reading it. Read it as many times as you can, speaking it out loud as you do. Listen to it while you're in the shower or getting ready and try to follow it in your head or speak along with it. It also really helps to try and learn it in english because you've translated it once when you wrote it the first time, so even if you can't remember the spanish in the exam, the english helps A LOT.
