    they'll be low but that low?
    They do seem too low in my mind. At a guess an A* in c3 will be 58-62 and an A* in C4 will be 59-64

    It was positive but less than 1 hence the decrease in mass

    Anyone else run out of time? I didn't even get a chance to attempt Question 7 and 8 properly
    Same here, I get extra time and dropped a good 20 marks bc of time management which is pretty gutting as this paper was relatively nice, especially compared to C3, so any chance I had of getting a good grade is fully down the toilet 💔

    Depends which side of the differential equation you put the +C on. If you put it on the left, then it was -pi, on the right is +pi. Either will be acceptable so long as it was the correct sign on the correct side..
