    I've done a bit of revision, tomorrow night, after my 3 hours sleep and history exam I am going to have to do some SERIOUS cramming, equations, life cycles of stars, learn how generators motors and dynamos work (we haven't even been taught it) and memorise like EVERYTHING... I hope the boundaries are low and the exams easy (doubt it) this year.. I really want an A.

    I think I'l be OK. Being last exam all Phys has been pushed out of my head by the other subjects though :/

    They're easy when you remembe the rule:

    in a series circuit voltages are shared

    So if you have a series circuit with two resistors, one twice as powerful as the other, then the voltage over the one twice as powerful will be 2/3 of the total voltage. The v-out and 0- lines are really just measuring the voltage over 1 resistor.

    To simplify: V1 ∞1/V2

    Ahh potential dividers... all I remmeber is Vout = Vin X R2 / (R1 + R2)

    This formula don't need to be memorised, You only need to know how to use it. Just remember the diagram there are two R2 and one R1. I rember like Rbottom, Rbottom, Rtop.
