Dear Math 293 students, December 24, 1996 Here are all the grades of all students in the class. This email will be listed in the course WWW page (http://tam.cornell.edu/faculty/ruina/www_293/home.html) under old email messages to the class. The letter grade is calculated by first calculating a big number. The big number comes from a complicated formula described in detail below. You can validate the calculation if you like. If the letter grade you compute does not agree with the letter grade shown it is because your TA used some of his limited supply of TA points to change your grade. The homework and prelims each have a median and maximum grade. Your grade is rescaled base on these medians and maximums. What part of course med max ^^^^^^^^^^^^^^^^^^^ ^^^ ^^^ HW Joel 8.4 9.7 HW Sergey 7.5 9.4 HW Tama's 6.9 8.6 HW Keith 8.2 9.5 HW Eric 9.0 11.3 HW Allan 7.2 9.1 Prel 1 84 105 Prel 2 74 105 Prel 3 88 105 Final Ex 59 98 Your homework and prelim scores are first rescaled by a formula of one of the two forms below depending on whether you were above the mean or below for the given component. The final exam is not rescaled. If you are below the median for that component, (Rescaled score) = (80/median) * (original score). If you are above the median or that component, (Rescaled score) = 80 + 25*((orig score) - med)/(max - median) The result of this scaling is that if you got a zero you get a zero. If you got a median you get 80. If you got the maximum you get 105. The lowest of the four numbers (rescaled HW and prelims) is dropped. The other three are averaged and multiplied by .65. To this is added .35 times the final exam grade. Then, the TAs added a few points for a few students. The resulting number was turned into a letter grade by the following table (which you might recognize as a MATLAB command). % cuttoffs for various grades. Number shown is the lowest number needed % to get the grade. cutoff=[ 101 % A+ 94 % A 88 % A- % 83 % B+ 77 % B 73 % B- % 70 % C+ 65 % C 62 % C- % 62 % D+ 54 % D 43 % D- % 0 ];% F Below are your grades. They are sorted by TA and the scores on the three prelims. Also listed are average HW scores, the final exam score and the letter grade. Incompletes and withdraws show up with calculated letter grades --- ignore them if you have a W or Inc grade.
