Read the lines aloud several times
Break the lines into small chunks
Focus on one chunk at a time
Repeat each chunk until it feels natural
Write the lines out by hand
Record yourself and listen repeatedly
Say the lines while walking or moving
Cover the script and recite from memory
Use cue words to trigger each section
Practice in the order you will perform
Rehearse with a partner or mirror
Sleep after studying the lines
Review again after short breaks
Test yourself without looking
Repeat difficult lines more often
