Hello Luca, and welcome to the forum.

Please be aware of the following policy (which can be found in the FAQ section):

In this forum we cannot allow direct help with homework or assignment questions, if we tell you how to do it you will never learn how to do it! We can answer specific questions and point you in the right direction, if you really don't understand your work/assignment then don't be afraid to contact your tutor as he/she will be pleased you came forward for help rather than struggle. One other thing, your tutor(s) may also frequent this and many other forums like it, either to help the community or sourcing training aids for their pupils so be mindful of this when seeking help!
Also, posting your e-mail address in a public forum is never a good idea - unless you like spam.
