I dont understand what the constraints mean
N∈{1,2,5,10}
N can only value values in this list: 1, 2, 5, or 10. No other values of N are valid
0≤ai≤100
Each of the N lines has a single value, which is between 0 and 100 inclusive.
In tests worth 3 marks, N=1.
In additional tests worth 5 marks, N=10.
These are obvious.
N
is the number of courses,
ai
is the grade for each course

If you still don't understand, you need to talk to your tutor.
