An electronics engineer's take on the DU cutoffs
If you don't like signals and systems, you should probably leave now. (PS : I'm writing this while under medication, so this might make sense to me only till the morn. Damn you fever! Edit : I read this again when in a better condition. There are unexplored analyses corners. I shall leave this as an exercise to the reader to figure out :-P ) TL;DR : Exams are too easy. Tough to differentiate. OK, I'm going to model the current examination and selection procedure very simplistically. The student is an deterministic function who can reproduce the same level of throughput at any given time plus a uniformly distributed random noise. Deterministic part says that the guy knows the answer independent of the situation he is in (like answer to 2+2). The noise accounts for the time variation of the student's ability - he may be sick on a day and not remember anything, or he may take a double dose of red bull and mug the entire text book. (or he may get access to a text ...
