Three full forms that could be contractions are: We all go to Millwood Secondary School. → We've all got to Millwood Secondary School. is not correct for this meaning, so the correct contractions in the profile are:

  • It is → It's
  • I am → I'm
  • I want → I wanna is not a standard contraction, so it remains I want.

The three standard full forms in the text that can be contracted are It is, I am, and They are → They're.
