    pedigrees and punnet squares

    Past papers, I suppose. My school gives us a booklet which has a lot of questions on these but I'm not sure if it's available at other schools.

    Titration Comp 21st June

    This is unfair. My teacher said there wasn't any vacancy left so she couldn't register for it. What the hell?

    4U Revising Game

    Why is it? I think his solution is typical and similar to what we've been taught... So you mean that it's not absolutely correct to put the Re = 0? Or you mean we have to include x =/= 2 and y =/= 0?

    The Dumbest mistake u've ever made in a Maths Exam

    (3/2)^1/2 = 3/2 I was supposed to find the ratio and I couldn't believe I squared the final answer. OMG.

    Identifying substances

    I don't think iron sulfates are insoluble in water since most sulfates are soluble except those of Calcium, barium, Lead, and some other very unreactive metals. If you're given samples of ferric or ferrous salts, be very careful because your tests can give positive indications to both of...

    treatment, control, prevention and management

    Treatment: how to 'defeat' or help the host body to 'fight' against the pathogens. Control/management: methods to manage the population of the pathogens, pretty much when the pathogens are still outside the bodies. Plus how to quarantine the pathogens, avoiding an epidemic explosion. e.g...

    4U Revising Game

    Can I just post the answers? Typing the whole solution is tedious. 1. ln6 2. use t= tan@/2 3. 4/11 4. pqr= 100*p +10*q+r = 99*p+9*q+p+q+r = 99*p+9*q+3A = 3(33*p+3*q+A) is obviously divisible by 3. Please check my calculations. hix

    phenotype experiment

    Gosh! We haven't done this experiment and we're half way through the 3rd module already! how ludicrous! I think the hydrangeas are of pretty good use. Hey, I like that rat! haha

    Soap & Detergent

    This is pathetic. I just digested the whole module in one week and now they are tumbling out of my head. :(( I know more for soap, I suppose. Raw material/cost: relative cheap and abundant since it's made from animal fats which can be attained from abartoirs, slaughterhouses, et cetera...

    Three Chemistry Calculation Problems (Preliminary)

    Er... what do you mean? That's the whole point of extracting Ni from its ore.: letting Ni react with CO.

    high UAI..

    Well, basically when you re-think about it, it's not THAT dire. I mean, when you are technically purposeless (like me right now), having someone to push you is rather necessary; because you know, if getting 99+ then I can choose whichever courses I wanna do later, right? (except for Med and...

    STAT (Discussion & Results)

    Re: Stat I'm totally depressed now. I have trials this weekend. Then real trials in 10 week time. Then UMAT around the same period. Then assessment tasks. Then application form for Med. Then... OMG! Don't you guys think of relaxing a bit before the STAT (i.e. Nov or Dec?)

    high UAI..

    People have different ambitions and they have different generalizations of their own abilities. Just aim for the highest and expect the worst. In this case: I'm aiming for 100 and expecting 99.95! lolz. Joking. My parents will kill me if I can't get 99+

    4U Revising Game

    Sorry to ask this but are we supposed to remember that rule for x and (a-x)? I've seen many questions but they always, kind of, giving hints by asking us to proof it first. Q: Find the volume obtained by rotating the region enclosed by the circle (x-b)^2 + y^2 = a^2 Where b>a, about...
