Ok well firstly what u need to do is write down on a blank sheet of paper everything that you saw during your experience- ( if that is given)
Secondly- i really don't understand this- but ill try to help!
Thirdly- If your asked to make an report then do what i had up above^
lastly- This probably didn't help but- again write down what is given to you and make sure that when ur writing everything down try to word it in a way you would in ur essay.
Again this probably didn't help but i tried at least.
