## Rule

A few challenging problems will be assigned roughly bi-weekly. Points are only given to **completely correct, or very close to completely correct answers**. For
each problem, if 1-2 people do it correctly, each person will get an
additional 1% of the final score. 3-5 people: 0.7%. 6-10 people: 0.5%. 11-15
people: 0.2%. 16 people or more: 0.05% (This means the problem is not ... that
challenging). You may share your answers with you friends (but you're also
sharing your points with them).
