Read paragraph aloud 3 times....
Say from memory the paragraph you just read aloud...
Check paragraph from memory to written paragraph. If there are any mistakes repeat these 3 steps until you've learnt the paragraph.
Setup a microphone on your PC or electronic device (laptop, desktop, phone, tablet, etc) and record yourself saying the paragraph/speech aloud.
Listen to your paragraph constantly whenever you get an opportunity to.
After reading the paragraph/speech and revising it, try to write it down from memory. Next write it down 3 times whilst reading it.
Hopefully these steps were helpful! I used these methods to revise for my GCSE writing exams and speaking exams.
Goodluck you can do it!
