Exams & Grading 
 
You can access your current grades for Astronomy 307 on
eGradebook.
  
Semester Totals were calculated according to the following formula (also see the syllabus): 
(1) take the sum of the exam scores, divide by 300 and multiply by 75; (2) add the best five homework 
scores, divide by 100 and multiply by 15; and (3) add the participation total (up to 10 points), which was based 
on the index cards, star parties, and Mather essay. On this scale, a perfect score would be 100.
  
 The Table below gives the letter equivalents for various numerical scores, including for the Semester Totals; 
 however, grades above 87.00 but less than 88.00 will be rounded up to an A, grades above 75.00 but less than 
 76.00 will be rounded to a B, etc.
