*BANG* *SLAP*

Professor Loi, sorry sorry I managed to start it up again!

#### The Awakening

The Chamber of Awakening, The Second Temple circa 2013

The last AMaths student has just left The Temple, leaving me alone in the cosy Chamber of Awakening to scribble out the suggested solutions to the 2013 O Level AMaths 4038 Paper 1, which has apparently created much angst and woe across the Twitterverse.

Angsty, indeed.

While the drilling from the renovation works at Udders Ice Cream downstairs is much less now, the United Square foodcourt has closed again for the day – leaving me stranded for yet another 吃风 night …

Access it here if you’re having trouble accessing it on Facebook using your state-of-the-art smartphone 🙁

Note:

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.

That aside, here’s the list of possible topics for tomorrow’s A-Maths Paper 2:

• Simultaneous Equations
• Matrices
– remember THE Identity Matrix (I) and don’t anyhow play with the order within your matrix equation har …
• Indices
• Surds
• Logarithms (hmmm … not so sure about this but just study lah!)
• Polynomials incl. Factor & Remainder Theorem
• Curves & Circles
• Trigonometric Equations
– where you go round (baby right round) the ASTC circuit with your basic angle)
• Graphs of Trigonometric Functions
• Further Trigonometric Identities i.e. Addition/Double angle/Factor formulae
• R-Formulae
– as R-Formula is NOT a given in your formula sheet, check if you need to derive it based on the number of marks in the relevant part
• Equations of Tangents & Normal
• Maxima & Minima Problems
• Area of a Region
• Kinematics
• – remember all the ang moh phrases i.e. “at rest”, “stationary”, “initial”, “constant”, “change direction” etc. and their meanings with regards to s, v, a and t

• And obviously, last but not least, please, please, please, for the sake of your 7-9 marks … may your 阴阳眼s of Plane Geometry come.

I wish those taking AMaths Paper 2 tomorrow, especially all poor O Level Biology students, All THE VERY BEST.

THE END (of this Hell Week) IS NEAR.

Till the next journal entry …

Professor Loi, I managed to start it up again!

What have I always told you about China-made nuclear products? *tsk tsk*

Anyway, let’s see what happened on O Level EMaths Paper 2 in 2013! I can literally feel their excitement a millennium later!

#### The Walls Whisper My Name

The Wall of Gratitudes, The Second Temple circa 2013

The last AMaths student has just left The Temple, leaving me alone to scribble out the much-demanded 2013 O Level EMaths 4016 Paper 2 suggested solutions, under the glare of the majestic Wall of Gratitudes.

Fending off the irritating drilling from the renovation works at Udders Ice Cream downstairs, as well as the despairing fact that the United Square foodcourt has closed for the day (which means another 吃风 night), I focused on the task at hand, with only the silent encouragement from the words on the Wall to spur me on …

As usual, please, please leave a comment should you spot any mistake in the solution. AMaths joss sticks sessions ended late tonight 🙁

Professor Loi, look what I’ve found!

said The Expedition Leader as he handed over a silvery object that was discovered moments earlier.

OMG it’s an iPad Air with Retina Display from 2013 A.D.! Do you think it can still be powered up?

Professor Loi, luckily I have one of those ancient “lightning” connectors which I have looted conveniently taken from another archaeological site. It should still be compatible with the USB 20.0 ports on my portable mini nuclear-powered charger unit!

*plugs in and powers up device*

OMG this is the personal device of the legendary High Priestess herself! And she did’t password protect it! *tsk tsk*

Let’s go kaypoh her personal journal shall we?

#### There’s A Light That Never Goes Out

The Welcome Shrine

It’s been awhile since my last entry – such was the long, despairing struggle against the invisible powers that be – but the monumental institution that is The Second Temple is finally about to see the light of day.

Meanwhile, however, there are more pressing matters at hand in the form of today’s 2013 “O’ Level E-Maths Paper 1, of which the only clue of what had gone on during the paper lies within this mysterious answer key produced by an even more mysterious tutor:

The mysterious GCE O Level 2013 EMaths 4016 Paper 1 answer key

That aside, here’s the list of possible topics for tomorrow’s E-Maths Paper 2:

• Algebraic manipulation & formulae
– i.e. changing subject of formula, simple fractional equations etc.
• Number patterns
• Percentages
– may still appear even though P1 already contains some
• Map scales
• Money problems ♫ money money money … ♫
• Graphs incl. plotting and tangent drawing
– a standard confirm chop stamp P2 question
– AMaths students you know what to do *wink*
• Quadratic equation to solve problems
– another standard confirm chop stamp P2 question
• Angles of polygons
• Similarity & Congruence
– incl. area/volumes of similar figures
• Trigonometry & 3D problems (just study lah!)
• Mensuration (surface area & volume of figures)
• Arc length, area of sector
– may involve some trigo & polygons here
• Properties of Circles
• Construction
– hmm … never seen this in P2 before though
• Coordinate Geometry
• Vectors (remember your curly tilde!)
• Mean, median, mode & standard deviation
– don’t assume you can always use calculator for this!
• Probability

I wish everyone All THE VERY BEST till the next journal entry, while the ceaseless work on the Facebook wall continues.

## It’s Raining Benefactors In June

(7)
Tuition given in the topic of Miss Loi the Tutor from the tuition centre desk of at 3:58 pm (Singapore time)

Another update:

Apparently, our in-house ‘chef’ is proving to be a hit among our participants!

Update:

Seems like many 小强s, 小明s and 小亮s have drawn the 上上签 this June 😀

Time to roll up the sleeves and 开工咯!

With an abrupt thud, she fell to her knees in front of the altar, oblivious to the choking joss sticks smoke swirling around her.

Mustering an immense focus that would triumph any muggertoad student’s, she began shaking the bamboo container of sticks in her hands while she uttered,

[translated from Cantonese]

Oh my divine deity. Please bless and advise me. My son 小强 will be taking his O Levels this year. But he just failed his Maths mid-year exam and from his exam script he doesn’t even know how to solve 1n+1!

Surely and surely, the shaking caused one of the sticks to emerge from the pile and drop to the floor.

Astonished, she quickly returned the stick into the container and began shaking it again.

Oh thank you my divine deity!

By the way, my 小强 also failed his Chemistry. And he still thinks that Mole Concept has something to do with cosmetic surgery!

My divine deity, please advise me what to do?

Another stick left the container and dropped to the floor.

Oh thank you thank you my divine deity!

Actually hor, my 小强 failed his Physics as well. Until now he still thinks that sea breeze occurs at night since his BBQ pit at East Coast Beach was disrupted by strong winds before a thunderstorm!

My divine deity, please advise me what to do?

Another stick dropped to the floor.

Oh thank you so much my divine deity!

Not trying to be greedy har … but my 小强 also failed his Social Studies. Errr … what is SBQ and SEQ har???

Can advise me one more time?

With everything “dropped and done”, she gathered the sticks and rushed excitedly to the temple’s fortune sticks interpreter.

Sifu! The sticks I’ve gotten all contain a φ symbol in place of the usual number. And all of them say I’ll “meet my Benefactor in June”. What does this mean?

The Interpreter took a cursory glance at the sticks.

Ah … another Last-Minute Buddha Foot Hugging case.

This φ symbol belongs to a newly-constructed Temple in the central part of Singapore, wherein reside the Benefactors who will be able to save the grades of your son.

June is the period when this Temple holds its June Holiday intensive joss sticks sessions for the subjects you have prayed for your child.

You may find more details at this Temple’s official internet website.

You better hurry, as June is just a week away and their joss sticks tend to go out of stock really fast – this is exactly the same thing I told the mothers of 小华, 小明 and 小亮 last week!
