When parallel parking on a driving test, am i supposed to put my arm on the passengers seat to look back? Or do i just look back and at my mirrors. My test is tomorrow and im scared ill suck at that. Aswell as when just reversing do i put my arm on the passenger seat?

My main questions are:

Do you rest your arm on the passengers seat while parallel parking on a driving test?

Do you rest your arm on the passengers seat while reversing on a driving test?
