E-Maths: Mensuration Formula Sheet

I have compiled a 'cheat sheet' to find volume and surface area of

  • cube
  • cuboid
  • prism
  • cylinder
  • pyramid
  • cone
  • sphere

This will be a quick summary for all students taking their O-Level examinations and school examinations. This will be useful for E-Maths students as the new syllabus includes a real life application question which can be testing on concepts involving these figures. It will be helpful for A-Maths students as well especially in their Differentiation proving questions. On top of that, A-Level H1/H2 students will benefit from it as well since it could required in their calculus proving questions too.

2015 GCE O-Level Additional Maths 4047 Paper 1 Post Mortem Not Solutions

After doing the revised syllabus 4047 GCE O-Level Additional Maths Paper 1, it reconfirms that Cambridge is testing basic concepts but presented in a different manner.

There are a few questions which are truly testing your application like the one on quadratic curve is always negative, range of m for which the graphs have two intersection points ...

I highly recommend all candidates to read your question carefully, keep asking yourself if you have answered the question.

An additional point to highlight is look at the allocation of marks to gauge the amount of working to present, the choice of approaches to use.

Based on what have been tested in Paper 1, we are looking forward to the following concepts in Paper 2:

  • Indices
  • Sum & Product of roots
  • Factor Remainder Theorem (solving cubic equations)
  • Equation of circle (*Draw if you don't understand the question)
  • Trigonometry R formula
  • The Hence concept (Differentiation & Integration combined)
  • Partial Fraction & Integration
  • Properties of Integral
  • Differentiation & Integration of exponential function and ln function
  • Differentiation: Eqn of Tangent & Normal
  • Coordinate Geometry
  • Equation of circle
  • Binomial Expansion
  • Linear Law

I would be expecting cross-chapters questions on Monday. Just like you, I'm a candidate so the above list is just my suggestion.

All the best for the final Maths paper. See you at the finishing line.

PS: Don't worry about bell curve! It's beyond our control!
