How would I go about learning my set text thoroughly and accurately?

You need to find the best possible method for you. 1. Make sure you read aloud your text, and record yourself, then listen to the text while you are walking, running, before bed, ect. 2. You need to be able to understand the translation, so use highlighters and underline which word goes with which, annotate your text 3. Summarise each scene, maybe with drawings if that works for you 3. Explain what is going on in the text to your friends, family ect.
