where to sign skilled worker application

[hardikshah01]

HI
I need to complete

Application
Schedule 1
Schedule 3 & family information forms

however only schedule 1 specifies that i have to sign and dated it?

does other forms need to be signed or only schedule 1 is required to be signed?

Shall i sent my passport size photos right now or it has to be submitted later on

advise
