Scoring method
The total amount of points in this test is 20.

To easily get percentages (which the test scores will be ranked on), I will multiply the total score (after getting questions right or wrong) by 5. This will equal 100.

The bonus question adds 5 percentage points to your total score. If you end with 92% and get the bonus question right, you'll get a 97%. See how it helps?

The highest percentage will win.

If there is a tie for first place, a tiebreaker worth 3 points will be given. This will continue until we have a winner.
