Here's the key: idno is the last four digits of your social security number, hwtotal is the sum of your homework scores, hwscore is the percentage on your homework, and mtscore is your midterm score computed by the formula mtscore = (hwscore*.175+e1*.13)/.305.  Notice that the grades for those who turned in all the homework are usually a letter grade higher than for those who missed a homework.
