contest among students. A total point is
calculated for every student who fulfills the
minimum requirements from 4 courses. There
is also maximum point (m) that students can get.
Weekly, every student has to fulfill the minimum pages
from the four defined courses. If a student fulfills
the minimum condition from all four courses, then
he gets 5, 5, 4, 4 points respectively for every extra
page that he reads.
