Near perfect. A couple of minor bits.

Also please update https://github.com/Unboxed-Software/anchor-movie-review-program to be https://github.com/solana-developers/anchor-movie-review-program and https://github.com/Unboxed-Software/anchor-student-intro-program to https://github.com/solana-developers/anchor-student-intro-program (these repos are already updated)

Do I have to update the sources as well ?

It seems that the repos don't exist on solana-developers org
