Little Ghost

The shadows were long this morning while students battled the AMaths monster (a new breed of Kaiju which no one had faced before) on Day 2 of O Level Halloween Week.

As I flitted along under The Temple Gates, distant “screams” from many voices stung my unearthly ears …

Regardless of what happened this morning, here’s the list of possible topics to attack and finish off the monster that is AMaths Paper 2 tomorrow:

As for those of you who simply need to get it off your troubled minds, here what I found when I floated to my Mistress‘ desk.

As usual, please, please leave a comment should you spot any mistake in the solution.

Notes from my Mistress:

  1. Before you ask questions like “I lost x marks in Paper 2, can I still get A1/A2/B3/B4/pass?” or “What is the cutoff for A1/A2/B3/B4/C5/C6/D7/E8/F9 this year?”, please understand that Miss Loi is NOT the Bell Curve Goddess.
  2. Please also understand that, unless things have changed, there is no half-mark awarded in O-Level Maths. Also it is nigh impossible for ECF if the part involved only carries 1 mark.

Good luck on your battle against AMaths Paper 2 – the last thing standing between you and mathematical freedom! Boo!

P.S. Last but not least, this could be especially helpful to those of you whose “hit-points” may be running low after this battle-intensive week.

    Hi! Thanks for the answers! For Qn5, i drew a best fit line with the last value as my "incorrect recording" (Really careless mistake :/) Yet i managed to get the answer for part ii and iii of the question. Is it possible to get some marks at least?

    🙁 is it a must to rationalise the answer in question Q2?
    I left the answer as 1/√26. How much marks will be deducted from that?
    I left out Q11 b) because i thought the answer for part a is weird and i am running out of time.

    Hi. For the linear law question, they asked us to estimate f. May we take the u and v values to evaluate f because that's what I did.
