    B.

    I was confused between A and B
    I think it's A because in B when the ray enters the glass it bends away from the normal but it should bend towards as it is slowing down

    Yeah that is good to hear I'm doing better than I thought I would so far

    What do you write for the opened question ?

    1. About the teacher and waves in a pond

    2. Aircrafts taking off
    1) Was kinda confused. Talked about how EM Waves travel at the speed of light and waves in a pond don't.
    Then I said something about them being waves

    2) Aircrafts with larger mass numbers have lower acceleration, meaning a larger distance has to be covered for take off.
    Something about unbalanced forces and acceleration.
    Then newtons second law and the equation.

    Yes , for 1 I talked about how they were both transverse waves.
    For 2 I talked about everything you talked about

    Yeah the similartieis were transverse waves, that's what I wrote as well

    Nice to see someone got the same as me. I'm usually terrible on open ended questions lol.

    The only question I found difficult in this paper was that aircraft open ended one. I talked about temperature and pressure, pretty sure I got that one wrong. What did you guys get?

    I'm pretty bad too in the prelim I got 2 out of 3 and 1 out of 3

    What did everyone get for one of the earlier questions about why certain values were being obtained for the voltage and current in a circuit or something along those lines?

    And also why would the person benefit from repeating the experiment or something along those lines?

    I think I got that wrong, I just said to increase reliability

    I wrote for accuracy lol. I don't think it's correct.

    I'm pretty sure it said How are different voltages and currents obtained ?

    Correct me if Im wrong ...
    What did you write anyway ?

    I said to ensure accuracy, and also noted how the person could also calculate averages. Luckily it was only worth one mark

    Yes it was that. I wrote by increasing or decreasing the resistance.

    For one of the early questions

    where it gave you 4 voltages and 4 currents ( I think)
    and then it asked you to find the resistance, what did you guys do with the figures in the table ?

    I talked about changing the resistance of the variable resistor
