Hehe I am taking advanced Stats next sem...as a choice of subject for my Maths minor...Originally posted by kaobeikaobu:a simple stats qn can easily make me looked retard...i can just look blankly at the qn...
dynamic algorithms...sure but sorry if i can't reply all ur qns...
wats the sample qn?
concurrent programming is another interesting subject...
Ok, the question goes like this. It is kinda long, but I will try to summarize it. If u feel like got sth missing, let me know.
It is near the end of the semester and you are taking n courses, each of them has a final project that you havent done yet. Each project will be graded on thef ollowing scale: It will be assigned an integer number on a scale of 1 to g>1, higher numbers being better grades. Your goal is to max ur average grade on the n projects.
You havea total of H > n hours to work on n projects cumulatively, and u wan to decide how to divide ur time. Assume H is a positive integer and u will spend an integer number of hours on each project. There is a function f(i), i=1,2,3....n, if u spend h<=H hours on the project i, u will get a grade of fi (h). Functions f(i) ar enondecreasing...Given these functions, decide how many hours to spend on each project so dat u max ur average grade. Running time shud be polynomial in n,g and H. -
Close Book Exam
Must memorize until you die. If the paper is too easy (e.g. MCQ) you will die unless you are ultra carefull. For a 40 question paper, you must score at least 35 and above to secure a B+. If the paper is very hard and you can do reasonably well for it then an A+ is most likely yours.
Open Book exam
If its those where you muz bring in 1 A4 size "cheat sheet" one then be prepared to bring magnifying glass. If you are truly shen, go for font size 3 then print it out.
I saw a friend bring in magnifying glass, he got an A for the exam
If its those open notes/book one and you have several textbooks then it all depends on your luck. If you heng heng can find everything with one flip then the exam is yours. Of course, carefull labelling with post tabs is a must -
oh oh.. i love stats too.. i love to be ruthlessly efficient at applying all those formulas. unfortunately though, i always mixed up independent sample with pair samples. -_-"""
biology is getting too technical. and boring... why the hell will i want to know how urea is synthesized in the body???

ah...I did the independent and pair samples thing before...it is kinda interesting tho...but yea, I tend to mix them up too...but sumhow my answer then turned out rightOriginally posted by starblue:oh oh.. i love stats too.. i love to be ruthlessly efficient at applying all those formulas. unfortunately though, i always mixed up independent sample with pair samples. -_-"""

best is to type your own concised notes. for my course, i will do a table of the key concepts i need to know. certain definitions, ways of application, names.Originally posted by rainee:dun have several books, but got lots of handouts...dats y so messy -
For open book exams, students should be provided with wide desktops.. so that one can spread out the papers/graphs/encyclopedias that one brings..Originally posted by rainee:dun have several books, but got lots of handouts...dats y so messy
Instead they provide a miserable square table where one leg will always be shorter than the other leg

they want you to use your handouts to slot under table leg to balance table. it is a conspiracy.Originally posted by DriftingGuy:For open book exams, students should be provided with wide desktops.. so that one can spread out the papers/graphs/encyclopedias that one brings..
