    Physics 12 GT

    Q was B :) Because they put options P, Q, R and (D) was none of these, I think. Q was the one with 2.0 m/s right?

    Physics 12 GT

    Who knows? I could be wrong, but the resistor HAS to get some P.D. cause it does have resistance. I got B for the ball one. Anyone else?

    Physics 12 GT

    I see, I see. I got 0.8 first too, but when I calculated it using a parallel circuit, I got 0.4. Why does it need to be 3v and 2v? They told us that one resistor (in parallel) had a p.d. of 1 v across it, so all components get the same p.d. in a parallel circuit, right? Also, you had to notice...

    Physics 12 GT

    Yeah I marked C for that one as well. For the current question, I put 0.1A, that's what I got with calculation... Also, for the diffraction grating one, I calculated it and I got less space, so I put that and sharper image, so B. What did you guys put for the one where we had to find the...

    So how was chemistry P12 today?

    I see, and which organic compounds cannot be dehydrated? I picked Ch3OH and the tertiary alcohol. you guys?

    So how was chemistry P12 today?

    I guess some people put 315 for the bond energy because in the Data booklet, the value of the C-C bond is 350, and because of energy losses the bond energy would probably decrease too.

    So how was chemistry P12 today?

    What did you guys put for the Ag+ and Nh3 question? I put A (all three options) and for the PVC one I put the bacteria and fungi option.

    The only good side to today is that we won't have to study for a few months :D

    Chemistry Paper 12 GT

    How was the paper guys? I thought it was okay, just got out of the hall. And when you vote, make sure you vote for the grade threshold not your expected grade...

    Chemistry MCQ thread...

    Q31: All you have to do is write down the combustion reactions for each compound. I'll write them below. C2H5OH + 3O2 = 2CO2 + 3H20 As you can see, for this reaction, 3 moles of O2 are needed so this is incorrect and we know that since 1 is incorrect, the answer must be C...

    Who's on Twitter here?

    Twitter has to be the best place to post about anything without worrying about your privacy too much. Follow me @wittybeast if you guys have one!

    Chemistry MCQ thread...

    23. The answer for 23 is D (correct me if I'm wrong). You can see that we start off with a basic organic compound, which is ethane and the final product is basically propane (with a halogen group), so the reagent must add ANOTHER carbon group to get from 2 carbons (ethane) to 3 carbons...

    Physics P-34 GT.

    Guys, how many possible marks can you lose? Technically speaking, you lose 3-4 if they're extremely strict, however I doubt that. If so many people made this mistake, then I figure they'll be a little lenient.

    Physics P-34 GT.

    lol I did the same, let's just hope there is, otherwise we'll probably lose 2-3 marks max.

    Lemme guess, yours was good? I found it kind of difficult because of Q1 and Q2.

    AS CHEMISTRY PRACTICAL DISCUSSION

    I just got finished, how was your exam? Mine was okay, messed up some readings though.

    Biology practicals 34

    It was alright. The questions in Question 2 were phrased a little differently, and the drawings were a little different than usual. How was yours?

    I take it you do remember :P What are you listening to nowadays? Do you have a soundcloud? How was your CIE result, if it isn't too personal? lol
