where did u draw the massive flowchart? across the lines they gave? rofl... thats a good way of filling up space :P

for that technique question, i said it was DNA sequencing.... cos you're comparing the sequence of the DNA i.e. order of nucleotides for a single chromosome.... and how can that be karyotpye analysis anyway, karyotype analysis involves looking at a karyotype, hence the name karyotype...

for that 8 marker, how can u talk about antibiotics not working....for viruses? antibiotics aren't for viruses in the first place and, wot does that have to do with them changing their antigen markers...

yeah midnight magick, youre right... nick's genotype doesnt matter...cos he only transmits the Y onto Jack.... thus colour blindness is determined solely by Maria's condition.... since she can either be normal or carrier....Jack can either be definitely normal or there is a 50% chance...

i wrote two answers: 0% chance of Jack being blind - condition: maria is normal (XBXB) 50% chance of Jack being blind - condition: maria is carrier (XBXb) this is assuming that Nick was normal, i.e. not colour-blind...

the answer is definitely D it says water molecules move from area of low solute concentratoin to high solute concentratoin, meaning that water molecules are moving from area of high water concentratoin to low water concentratoin....and it has to be osmosis... not diffusion :D

that question was totally fucked...not in the syllabus according to the way it was worded i ended up talking about out of africa and regional continuity cos thats the only two theories that we have learnt!!! they better compensate, i reckon, for all those who did human story for that...

im standing on 82 after realising i made two sillies... *sighs*

yeah i agree...they should accept 0.7, but they should accept 0.8 as well :P

pfft.. as opposed to other yr's maths exams which weren't about putting off people - which were about making sure that everyone shined. rite...

the question said use the method of halving the interval to find AN approximation... this doesnt' neccessarily mean an approximation with one try of the halving interval or with two tries or with three tries or whatever... because this is not specified, both answers are acceptable...

i found i lost a mark.. hoping for 83

sliderule, my understanding is that firstly when u arrange one set around a circle, the elements can be arranged in (n-1)! ways. This is the basic formula for arranging n elements around a circle... but when u have to arrange the second set of n elements, such that they alternate, the no. of...

i think this hard integration question is answered sufficiently

sliderule basically expanded the brackets thing... then he got the expressoin 3 (t^2 - 3t + 2) and then splitting those up, you can get sum of all the t^2 's and the sum of all the t's and sum of all the 2's.... and so forth butttt u need to know the formula for (or be able to derive)...

wot u are saying is so nonsensical... can u clarify???

just one thing to be clarified for myself, some people have C's and some have factorials in their solution (it always happens with perms and combs)... does it matter which 'approach' you take in solving these types of questions? cos my ans: 6X7X6! = 30240 as well...

it doesnt matter...both he and you are correct... this is because if you take the '2' out you will get ln 2 or something along those lines, which is a constant c anyway...

i apologise for any dubious interpretations of wot i wrote previously... but the fact remains that the part of the curve in between 3 and -3 should meet the asymptote y=x at x=0 only, not like in terry's solution, where they are meeting at three distinct points... and the other mistake...

there are a few mistakes with terry lee's solns that i found... like the graph question, the part between -3 and 3 shouldn't cut the asymptote y=x and in the complex no. question, the extremities of the diameter of the circle, at (1,1) and (1, -1) should be excluded with 'little...
