CSE 428, SPRING 98 Algorithms for computing the relative score you have accumulated so far, and for computing the final grade, depending on your performance in future HWs (#7, #8, #9) and final exam. Thursday Apr 9, 1998 ============================================================================== Rationale behind the algorithm: 1) HW #8 will be about Prolog, and HW #9 about Object Oriented programming (C++ or Java). they will be worth 60 points each. 2) Therefore, the score of the past HWs (#1-#6) has a relative weight of 57.9% wrt the score of all homeworks, while the score of the future HWs has a relative weight of 42.1%. 3) As you remember - the HWs in total count for 40% of the total score - the MTs in total count for 30% of the total score - the final (comprehensive) exam counts for 30% 4) Tentatively, the correspondence between the score and the grades A-F will be as follow: After normalizing the scores to 1-100, A will correspond to the interval 80-100, B to the interval 60-79, C to the interval 40-59, D to the interval 20-39 F to the interval 0-19 "Tentatively" here means that the exact limits of these intervals will depend on "borderline cases". In other words, I want to avoid that a lot of people gets a B, for instance, with a score of 79,9 when the limit is 80. So I might have to put the limit between A and B (or between B and C etc.) in slightly different points. (Which point exactly will be determined mainly by the score of the "borderline people" in the Midterms and final.) ============================================================================== A) Algorithm to compute your relative score so far 1) let Th be the total score of your past HWs let Ph = Th / 330 let Sh = Ph * 0.579 * 0.4 * 100 2) let Tm be the total score of your Midterms let Pm = Tm / 160 let Sm = Pm * 0.3 * 100 3) let S = Sh + Sm S is your score so far in the scale 1-100 ============================================================================== B) Algorithm for computing what you need to achieve in the future HWs and final exam in order to get a certain grade g 1) Let L be the lower limit of the interval associated to g according to the table above 2) Let Ls = L + 5 (this is for taking into account possible shifts of the limit of the interval) 3) Let x and y be the "unknown factors", i.e. how well you will perform on the future HWs and final exam, in percentage. 4) Consider the equation Ls = S + (x * 0.421 * 0.4 * 100) + (y * 0.3 * 100) 5) Play with x and y. For instance, if your score so far is S = 40 and you want to get at least the grade B, then you should - get at least 25% of the score in future HWs and 70% in the final or - get at least 70% of the score in future HWs and 50% in the final or ... (infinitely many possibilities, of course) ==============================================================================
