    10.2 from the main cm scale and then you read off the vernier scale, which had 7 divisions, every division was 0.01cm therefore 0.07cm

    10.2+0.07 = 10.27, This is how I did it, gotta wait for the Mark scheme to be sure of the exact answer.

    Thanks, man! Makes sense, but most of my friends got 10.70. Also, vernier constant is 0.005 cm right? So don't we use that?

    Hey Guys. I have a question, a silly one though. For the refractive index diagram I drew it in the empty space below the questions. Is that okay.

    Wrote the same answer, as both of you.




    The %Uncertainty, had to be given in 2 s.f rather then 3 s.f because the data given in the question was 2 s.f max.

    I think, I remember writing 7.9 (%) as the answer.


    Did not get a negative gradient whatsoever,

    Must have gotten confused then.But It didn't pass through origin

    Did some of ur answers look like this?:

    multiple choice: A,D,A,B,D (directly proportional, velocity, 10.27, can't remember the other 2)

    7.9%
    gradient: 4.5
    resistivity: 1.1 x10^-6

    I didn't think it was too bad wbu
    Got all the same answers, except 1st MCQ was linear as it didn't pass through the origin, it cannot be proportional.

    Are we talking about the last part of question number 6? with the trolley?
    *Sigh* I ended up writing the range 2.97-3.03 s for the time given(3s) and then wrote whatever value you get within that range,You can round that off to 3s.Would I be able to score atleast 1 mark or was that completey wrong?

    I did the same! I was reconsidering drawing it on the main lined page but ran out of time. I mentioned stuff like "As shown in the diagram in the previous page.." in my answer though

    Well, for me I also said that for part b I have labelled the stuff on the diagram, I didnt mention last page though.

    For the refractive index, question B asked to show on the diagram the quantities to be measured
    We just had to draw a normal line and show the angle of incidence and refraction right?

    Btw what do you think the grade boundaries will be guys? I doubt it's gonna be 35.In the previous 5 papers It has gone above 30 twice.Once at 31 and once at 33.

    33 +- 1 in my opinion. I wonder if I'll grab an A, a B is for sure though.
