hey rachel,
haha no worries, the way i understand it, they only recommend that you complete that form before the 5th. You can even do it during freshers week with your tutor (I thhink - someone correct me if I´m wrong!). Preadvising you can find here:

and your password and username is the one you chose for your computer account as well (you´ve done that?)
Then you have to look up the core modules for your subject. (In the course catalogue) Those are the ones you have to do. Enter them. But usually that doesn`t fill up the minimum amount of credits per year(120 I think) so you have to chose other modules as well. Generally these will be 1000 Modules, but not always. Be careful when you do that that all the modules don`t clash timewise, and also, sometimes they are only taught in one semester. It took me a lot of scrap paper to figure it out!
lol
I think that´s it, hope it helps!
