Hello guys I just started a certificate III in civil construction about a few days ago. My problem at the moment is I like got confused or something from my anxiety, they gave us assessments to do and had question like, what does JSA stand for or explain why everything on a work slip needs to be recorded and signed. They gave us these like other text book things but idk why i never looked at it and just came to me now that we are supposed to get the answers from there, thats why i left class because I was think wtf how am i supposed to know this when really i think it was all in the text book. now i feel ****, depressed and like the biggest dumbass ever.

Should I go back there and hope its not too late and ask if i can start all over again?
