The neg is no problem mate, don't worry about it
(I don't want to spam the thread with offtopic posts)

Hello melatron, ur thread on the Latin language 1paper june 12 mark scheme was so useful, do u happen to have the language 2 paper for the same year? Thank you!

and it will take time trust me, you need to dedicate hours each day if you even want to have a chance of making BMO2 next yearother more olympiad-specific articles by yufei zhao can be found with a quick google search (hes a past IMO contestant for canada)thats about everything I can tell you, bit rushed right now

also at some point in working through these books it is highly recommended to go through the following booksrecalculus (aops)calculus (aops)Precalculus one should really be done after you finish the introductory aops series of books but i did it first because my parents already taught me number theory/geometry/combinatorics (intro) from chinese text books before I was in year 8 so I had a good problem solving background already,Also another point is that don't just do books - keep trying out problems from different olympiads - very good resources section here:http://www.artofproblemsolving.com/F...sources.phpand keep trying SMC problems too, dont give up, you wont improve AT ALL you need to actually think about problems to become better

well the ones i used are:
GEOMETRY:
aops intro to geometry -> plane euclidean geometry (UKMT) -> geometry revisited -> prasolov problems in plane geometry -> challenging problems in geometry
COMBINATORICS:
aops intro to counting and probability -> aops intermediate counting and probability -> generating functionology -> 102 combinatorial problems ->mathematics of choice
ALGEBRA:
aops intermediate algebra -> algebra (by im gelfand) -> 101 problems in algebra (feng/andreescu) -> complex numbers from a to z
INEQUALITIES:
just look for articles on artofproblemsolving.com or use UKMT's inequalities handbook (not very user friendly if you're new to olympiad maths though)
Polynomials:
I personally learnt most things I know about olympiad polynomials from taking WOOT class on aops
NUMBER THEORY:
intro to NT (aops) -> intermediate NT seminar by aops -> 104 problems in number theory (zuming) -> number theory article by 'nsato' (abbreviation of his name) -> any other olympiad number theory articles
PROBLEM SOLVING BOOKS:
problem solving strategies (arthur engel)
maths olympiad handbook (not teh UKMT one!!)
Art and craft of problem solving (zeitz)

Thank you so much

Hi ya have you got aqa c3 and b3 jan 2012 aqa please? thank you

hello do you know when aqa CHEM grade boundaries out?

hey im really worried for my P2.. can you give me an honest answer please on what you think i might have..
1a) Friction between the pipe and the beads causes electrons to be transferred from the pipe to the beads and negatively charged
ii) 75cm cubed beads
iii) As size increases, charge decreases
b) All of the charges decrease as the pipe is shorter so there is less friction
c) Fine particles- dont need as strong spark to ignite them
ii) Earth the pipes
iii) Temperature, pressure and other variables might affect the MEI value/ results
2a) Nuclear fusion is the joining together of small nuclei to form large nuclei whilst nuclear fission is the splitting up of large nuclei to form small nuclei. Nuclear fusion needs extreme temperatures to take place whilst fission doesn’t.
ii) Heat
b) i) Uranium -235/238
ii) Same number of protons
3a) Constant speed, accelerating, decelerating
b)thinking distance?
ii) worn tyres
c) i said the size would be smaller due to the crumple zone reducing the force exerted on the car and the direction is towards the car.
ii) To measure the force exerted on the dummy
iii) 10m/s^2
4 a) 2V
ii) i done a curve going through 2,0.8 and then rising up to 12...
iii) Because voltage increases?
b) 108J
5 a) Pudding was positive with an equal but opposite charge to the electrons
b) Experiments didn’t support pudding model but supported nuclear model
ii) went straight through going not near any nucleus as it wasnt deflected, then i said for B that they were near a nucleus as positive deflected them a little bit and C hit the nucleus deflecting all of alpha particles
c) Results provided evidence for Rutherford’s theories suggesting his theories are right
6a) 98,000 J
b) 5.6 kgm/s
ii) 5600N
iii) Increases time catching the ball, decreasing the rate of change of momentum, reducing the force on the fielder’s hand.
