  • The max score on every challenge is 100 points.
  • Partial credit is awarded on some challenges. A participant’s score depends which test cases a code submission successfully passes. Certain test cases are worth more points than others.
  • If a participant submits more than one solution per challenge, then the participant’s score will reflect the highest score achieved.
  • Participants are ranked by score. If two or more participants achieve the same score, then the tie is broken by the total time taken to submit the last solution resulting in a higher score
