I left out these last sentences.
Thank you.
1) My parents like my clothes style very much and not
They like so much my clothes style.
2) My favourite style is the urban look because it is comfortable enough for school.
3) Each of you will have to join one of the four groups depending on his or her own interests.
4) Each Group should include at least six pupils. You can get the information online or by carrying out some research in the school library.
5) After gathering the necessary information you'll have to upload them on the Platform.
6) You'll log in (you'll access the Platform) by typing the username and password I gave you.
3 and 5 = comma is needed in each sentence ... can you see where?
4 = no capital G needed on "group"
Everything else is fine.
