Final invigilation duty of the summer term: one candidate sitting the Edexcel Advanced Extension Award in Mathematics (a bit like the old S'level).
Frustrating, as I couldn't write anything down - did as much in my head as possible though. I sympathise with any non
-mathematician invigilating this one - 3 hours and a paper full of algebra! However, for me it was a joy, keeping my mind ticking over for pretty much the whole time.
Having to be aware of possible external disruption e.g. noise at change of lessons etc, not to mention anything required by the candidate, I couldn't devote my attention to the algebraic manipulation necessary for some sections - after all it isn't designed to be done in your head!
"The sum of the first p
terms of an arithmetic series is q
and the sum of the first q
terms of the same arithmetic series in p
, where p
are unequal positive integers.
Giving simplified answers in terms of p
(a) the common difference of the terms in this series,
(b) the first term of the series,
© the sum of the first (p
) terms of the series."
Had enough yet?
