Each entrant has been assigned a code. The code is the initials of the student's name as listed on the entry form, followed by a two-digit number. The number is the sum of the reported grade in school and the last two digits of the reported zip code in your address on the form. You can request a change in your code for subsequent results by sending an email message to Dr. Bill Martin in which you give the two letters and two digits you wish to use (be careful not to use something already assigned in this list). Contact Dr. Bill Martin if you cannot identify your code. Each problem attempted was given a score of 0-5 using the following rubric: 5 Completely Correct 4 Essentially Correct with minor flaw or omission 3 Substantial Progress, but with significant flaw or omission 2 Some progress 1 Little progress, but with some valid steps 0 No progress A blank indicates that the problem was not attempted. Final results will be based on both total points earned and total problems solved or essentially solved (as indicated by a score of 4 or 5).
