Final Exam Grades

The mean on the final exam was 67%; therefore a 3 point curve correction was added. You can see your final exam score, including the curve correction, in the Final Grade file below.




Please read the following carefully.



Your letter grade is calculated by adding up all your points and then dividing by 500 to get your course average (XTOTAL). NOTE THAT XTOTAL IS PERCENT OF TOTAL COURSE POINTS; 5 POINTS EARNED DURING CLASS = 1% OF YOUR TOTAL COURSE SCORE (5/500 = 1%). This means, for example, that if your XTOTAL = 73 (a letter grade of C) that you are 10 exam points away from XTOTAL = 75 (a letter grade of C+). Use the grading scale (see below) to get your letter grade (LETGRADE).


Please note that point totals, not percent scores, are given for each exam. Exam 1 was worth 54 points, Exam 2 was worth 54 points, Exam 3 was worth 78 points, Exam 4 was worth 64 points, and Exam 5 was worth 100 points. Exam curve corrections have already been added to the exam scores. Students who took the makeup exam will have the point score for the exam they missed listed in the MAKEUP column; everybody else will have 0's in that column.  


Students who attempted 80% or more of the Top Hat questions received full credit for correct answers (i.e., number correct/number tried); students who attempted fewer than 80% of the questions lost 30% of the Top Hat points they otherwise would have earned. Your total Top Hat points are under ADJTOP; this was calculated by multiplying the fraction of Top Hat questions you got correct by 50 (e.g., if you got 83% of your Top Hat questions correct, and you answered at least 80% of the questions, your score is 0.83 x 50 = 41.5). 


Your total points for the lab are presented under LABGR. Lab sections 9 and 11 had significantly lower means than all the rest; students in these labs received a 4 point lab curve correction which was used in the calculation of XTOTAL. EFFORT is your lab participation score; a score of 1 (good participation) enabled you to move up a grade if you were on the borderline between two letter grades, a score of 0 (poor participation) prevented you from moving up a grade if you were on a letter grade borderline.
