Repeated measures ANOVA- reshape data?

I assessed HIV knowledge at pre, post and follow examinations. It was the same exam 14 items for pre, post and follow-up. Also The same participants completed pre,post and folow up. My data is in wide format. If i want to do a repeated measure ANOVA (this was suggested to me), do I have to reshape my data? I would like to conduct a test to see if there are difference between pre vs post, pre vs follow and post vs follow.

What is the correct test?

Thank you,
