    PSA1 - was alright - not the easiest paper i have seen though - probably just average - i thought that PSA2 was pretty hard to be honest.

    Disliked the question about the guy using baloons and upthrust - volume etc...i had a go at it using all the viscosity stuff from Eat but no idea if i got it right.

    Didn't get what they were asking for on the question with the resistivity - depth graph when you had to write an equation for the line of the graph.

    edexcel B, as for upthrust was it equal to weight or air + helium?

    yah the question on the guy with the balloons was pretty tough. I couldn’t work out the upthrust…. Btw did u guys get something like 60m^3 for the volume we had to calculate?
    It also took me ages in the exam to work out the resistivity question…. Sorri but that scale was fked up.
    Unit 1 was not bad, apart from that odd question 2…..
    How did others find it??

    i got 62.9m^3

    btw, for paper 1, wt did u guys get for the efficiency? 3 marks... i got like 94%...

    how did u get 94%???
    i toke the answer for how much maximum energy can be supplied per day * amount of days in year, then how much it produced in a year (it was given)/ tat figure i got 0.8 or 80%

    I can't really remember much about the question but i think:

    The maximum energy supplied per day (given to you in the data) divided by the energy used/generated by the power station (you had to calculate in the first part) X 100 - basically a normal efficiency calculation- came to about 94.7% i think.

    Could be wrong - like i said can't really remember each part of every question.
