2013 GCE O-Level Additional Maths 4038 Paper 1 (Post Mortem)

Observations for 2013 GCE O-Level Additional Maths Paper 1: Graph on linear law, partial fractions, binomial, nature of stationary points, decreasing function, coordinate geometry, exponential word problems, sum & product of roots, proving identity, factor formula, modulus, rate of change, hence qn on dy/dx & integration.

Based on what was tested in GCE O-Level A-Maths 4038 Paper 1, the following concepts are yet to be tested:

Trigonometry equations
Trigonometry graph
Indices
Matrices
Kinematics
Plane Geometry (very likely)
Gradient of tangent or normal
Logarithms
Factor remainder theorem
Relationship between curve and line
R-formula
Equation of circle
Area under curve

We look forward to 2013 GCE O-Level A-Maths 4038 Paper 2!
Do your best and check your work to achieve perfection!

2013 GCE O-Level Elementary Maths 4016 Paper 1 (Post Mortem)

It's interesting to see hemisphere and hemisphere. There are a few PSLE level Maths questions as well.

Based on what was tested in GCE O-Level E-Maths 4016 Paper 1, the following concepts are yet to be tested:

Scales & maps
Men & houses
Subject formula
Number patterns
Graphs (Definitely a question)
Quadratic (Definitely a question)
Compound Interest & other everyday Maths applications
Polygons
Construction of bisectors
Congruent & Similarity
Angle properties of circle (again?)
Arc length & area of sector
Trigonometry
Vectors
Probability
Mean & Standard deviation

We look forward to 2013 GCE O-Level E-Maths 4016 Paper 2!
Do your best and check your work to achieve perfection!

All the best for GCE O-Level Elementary & Additional Maths exams 2013

Breathe
Believe in yourself
Bring all your required tools eg Mathematical set, 2 calculators, french curve, long ruler
Circle keywords
Do + think fast & accurate
Calculate carefully
Plan at least 20 minutes for checking for every single O-Level Maths papers
Check your workings + use other approaches to double confirm your answers
Answer to the question
Draw a decently nice graph
Write clearly
Cancel wrong workings neatly
Turn your head to prevent neck-ache
Take a sip of water to relax your mind
:) at the questions & enjoy the papers!
Make the job of your markers an enjoyable one

A-Maths: Plane Geometry Question (Step-by-Step) [Video]

In this video, I will show you:

How to prove that 2 lines are // to each other
How to prove a pair of similar triangles
How to prove an equation involving length

Properties & Theorems used:

Angles in the same segment
Intercept Theorem
Corresponding angles
Tangent - Secant Theorem

Strategies (Used in manipulation in part iii) :

Breaking a longer length into smaller parts
'Expansion' of length
Using result from earlier parts
Factorising common length

A-Maths: Plane Geometry (Geometrical Proof) Mastery Workshop + SPECIAL CODE

Student 1: "I can't see!"

Student 2: "I don't know how to start. I don't know which theorem or formula to use."

Student 3: "I always can't do plane geometry question in exams!"

Student 4: "I don't understand the topic at all!"

These are the common problems faced by many A-Maths students in the topic of Plane Geometry, even A-grade students!

Every year since 2008 in GCE O-Level Additional Maths Paper 2, there's always a Plane Geometry question worth 8 to 10 marks!

This topic can be made easier by

Looking out for hints given in the question and diagram
Understanding the newly introduced theorems (5 of them)
Combining E-Maths angle and symmetry properties of circle
Learning the 'dummy-proof' way to prove congruent and similar triangles
Exposure to a variety of strategies and questions
Learning how to apply the skills learnt on solving questions

I'm conducting my final A-Maths Mastery Workshop on Plane Geometry this September!

Join me for this final revision and solve that Plane Geometry question in O-Level 2013, add 10 marks to your final score!

E-Maths: Reading of Cumulative Frequency Curve (+ Pie Chart)

A parent recently sent me some questions and I would like to share with you this one on Cumulative Frequency.

The tricky part of question (c) is reading the scale correctly.

Every small square is 2 units on the x-axis
Every small square is 4 units on the y-axis

For (ii), total number of students (160) represent the entire pie chart which is 360 degrees.

Therefore, by proportion, we can find out the degrees of the pie chart for students who are awarded C grade.
