Hi i am currently in year 10.

I got an n award for maths because i didnt complete a booklet that was handed out.
If i resolve the n warning but i get an e in math ( i know i will ) does it mean i fail the subject?
If i fail maths will i have to repeat all of year 10 or can i just repeat the maths course? Will they make me repeat every subject including electives? Even if i do good in every other subject. Please help i dont want to repeat all of year 10.
