I did mine last season and we spent virtually a whole day playing football. Unless it’s changed this season, I thought there was still that element.Packed lunch, drinks, 2 pens or pencils, indoor footwear and football boots, a large notebook, and warm clothing in case the outside sessions are in the rain. Go already dressed for outdoors, if weather not great put a tracksuit or similar on over your kit.
Not sure why they want you to have shinguards as there is no practical game play in the course now.
Most importantly ask lots of questions and get involved. Enjoy!
