Alright, prelims are 2 days away and I can barely wait. You see unlike most of my friends who are dreading the prelims 'cos they're afraid of messing it up, I honestly can't be bothered anymore. All that the prelims have done was to make me one pissed off fella who has been stuck at home for the longest time ever, been unable to play dota freely and anytime I'm not revising which is most of the time, there's that little niggling warning at the back of my head. So as one can see, the prelims are a thorn in my side and therefore I simply can't wait for it to be over. And now just for the fun of it, let’s see how many ways I can pass my prelims. Assuming grades of A, B, C, D and E to be pass grades and the fact that I would still like to pass all my subjects, that means 5 different grades for 5 subjects each! So it'll probably be 5^5 because every subject is independent of the other, and the grades can be repeated and order doesn’t matter. So yea, 5*5*5*5*5 = 5^5. Woots! I've just revised permutations! And based on that, the probability of me getting 5 As is 1/3125 but the probability of me passing with any other grades is 3124/3125 which is 99.968%! Thus, one can see that aiming for 5 As is an inefficient allocation of resources. Hence, I should simply aim to pass because the chances of doing so are higher and this translates into more slack for me (I.e. Higher margin for error.) So folks, don't pressure yourselves too hard for prelims, as I've proven somewhat, passing isn't all that hard. In fact according to my (flawed) theory, one has a 99.968% chance of passing! But (in the words of some advertisement) why take my word for it? Try it for yourselves! Oh not to mention there'll probably be moderation too if enough people screw up. That means, your chances of passing is close to a 100%. Alright, enough for now, the real deal is in 2 days time. Till then, have fun mugging!
