    yeah true, someone else was saying about a thermal physics question which could be likely, maybe an isa style experiment, which would not be good haha
    I sure hope not! Ahah, could not cope with an ISA style one... Ah well we'll find out tomorrow I guess!!

    Usually two papers are written for each unit each year just in case there is a leak or something.

    Apparently a van containing AQA exams was stolen so we will most likely get the other one they writ.

    Nope don't think so.. Just checked news now and AQA is saying Physics papers will be unaffected.

    1u = 1.661*10-27
    1u= 931.5MeV
