I need would like my course materials early
They come in 2 parts - 1 for 1st Nov & 1 some unspecified time in the future
I get a week off at Christmas & I could really forge ahead.....but if they arrive in Jan I can't. Plus I have uncertain health & it's tricky to plan.....knowing my luck I'll be ill at Christmas 
So I'm cheating a bit - does this work?
"I received the confirmation email that I am booked onto this course; I would really appreciate the course materials arriving early as my health (wrt to my Chronic Fatigue Syndrome) is so uncertain that any time that I am 'healthy' and able to work I would like to start on the course and get ahead so when I do (inevitably) get poorly I will not fall too far behind. I understand that it comes in sections but would hope if I manage to finish one early (which tbh is unlikely) I could request the next bit.
Don't worry if it's not possible as if I have been poorly before I have been given extra time by the tutor to complete the assignments but obviously that is less than ideal as it affects marking schedules."
or not?
