Summation of ( \frac1r(r+1)(r+2) ) using partial fractions. Students had to find the intersection of this

Be cautious of unofficial solutions. The 2012 paper's vector question has been solved incorrectly by many amateurs. Cross-reference two sources if possible. Summation of ( \frac1r(r+1)(r+2) ) using partial fractions

As Wei scribbled the final line of the proof, the hum of the library lights seemed to crescendo. He reached the end.

A common trap in NJC papers is the Central Limit Theorem (CLT) application. The question likely provided a non-normal population with a sample size $n$. Students had to explicitly invoke CLT to justify the use of the Normal approximation for the sample mean. Failure to mention "by Central Limit Theorem" usually costs method marks.
