    How did you find maths Paper 63?

    90% would mean you did better than 90% of the candidates-or in other words you were among the top 10% candidates taking the exam. Cheers.

    How was chemistry paper 23?

    I am from Brunei. According my classmates the equlibrium. quest the answer is x=1/15 so final=no.of moles-1/15 The mass of CO2 was 12,000,000 tonnes :D Last part about the car distance. 1.39x10^11 God bless

    Yeah I got those too, I just missed the last part.

    Physics Paper 23

    For the electricity question I did someone like V=IR for the first two parts (I used it somewhere to find I I think, and later put it in the equation E/R+r=I so yeah) I left the last part lolll. The last part has something to do with internal resistance.

    Oh I am from Brunei. Only Brunei and Malaysia are sitting for P23. Any paper ending with 3 practically. All the best!

    and I think....I got k=4...It has been some days so I got a bit, you know.

    Physics Paper 23

    Since Power is constant 576/8=R Resultant Force=72N Subst. it below 72N-R=80X0.5 R=32N Well was the combined mass 80kgs? Than this should be the answer for the next part of finding the R Thanks

    Physics Paper 23

    Resultant is 32N(someone said 35N, so yeah) for v=8.0 ms-1 (acc. 0.5 ms-2) I wrote colours of the waves since they said NEAR 500nm. I may be wrong. Velocity of the plane is....225 or something.

    As for S.F, we're supposed to use the same SF as given in the question.

    Physics Paper 23

    I think the resistive force was 42N. It turns out to be proportional with k=3.

    so how was physics p2?

    Daniyal, we both sat for P23 dude (are you from Brunei too?) Yup I forgot to convert the eV to J as well. However writing the formula would give you at least one mark. (at least 1). Electricity...I messed up the Last part. That's two marks. I think first three parts were alright.

    I didn't ask about any chemicals or anything ( I'm from Brunei and our papers are COMPLETELY different that Pk's) However if there is any misunderstanding I apologise however I was just trying to ask about hints on how to recognise gases as I am not sure when SO2 or Co2 or NH3 is produced :(...

    Chemisry Practical 35 Guidance Needed

    Hello, I will sitting for my Chemistry practical 35 on the 25th of October. Maximum error of burette would be appreciated, as well as titration calculation (I usually just get first three calculations correct :p) Also how am I to identify the gases produced even before doing the...
