    Aaaaaarrghh! That was sooo hard,
    I know that I have dropped at least 20 marks and am hoping the grade boundaries will be really low, perhaps 40/60 for an A? I hope I can just scrape a B -really don't want a C...

    Does anyone know for the bird question what it meant by work out the number of oscillations?
    And what did you draw for the last question for the graph?

    I got that too!

    did you use the 3.14 ohm resistance then?
    I wrote the resistances in the table as 3.14 and 21. something ... as in 3sf. did u do the same? and is this okay seen as apparently the table was all in 2sf

    Yeah, I got the same - though I put the length of the wire as 0.02 metres - there were a few grey areas in terms of sig fig on this paper i thought

    I may have used 3.2 ohms because I can't round, but yeah thats what i used since 20 degrees is likely room temperature. With 2014, since it was very hard there were far less significant figure penalties compared to other papers, so it will likely be the same. What did you guys get for the sensitivity of the microscope?

    **** I got 0.18m

    I think the question tripped me up somewhere or I missed a zero on my calculator

    I got 695, but the answer depends on the tangent you drew

    Do you remember the raw figures you got off the graph?

    what were the units? I think I missed something

    The Units weren't standard, they were the same as the ones on the graph including prefixes
