Confused!

This lesson was not so good :( i accidentally got a bit confused with what was got to be done and i for some reason i took apart my lamp thinking i had to do that because my aluminium was turned inwards and i thought that because everyone else's was outwards i pulled it apart to try to put in a big hole for the wires but then mr Ward helped me and said to put it back together and then the bell went so i didn't have enough time to put one in :( at least it was a lesson learnt!
