Time Management: The paper is lengthy. The "show" questions (Prove that...) are designed to be quick if you know the trick, and time-sinks if you don't. If you are stuck on a proof for more than 5 minutes, move on. The subsequent marks are often independent. 2012 njc prelim h2 math
A specific section of the Paper 2 marking scheme provided the following solution for Question 1(a): Given: Modulus calculation: Argument calculation: Resources for Revision
One of the most notable problems in Paper 2 required students to find the greatest possible value for the argument of a complex number that satisfies a specific circular locus. The Problem: The locus was a circle with center and a radius of 3 units. The subsequent marks are often independent
Vectors: NJC vectors questions are notoriously abstract, often testing the relationship between lines and planes, or determining if lines are skew, parallel, or perpendicular without simple numerical coordinates. Paper 2: Pure Math & Statistics (40/60 Marks)
NJC 2012: Often conditional probability with “given that” and tree diagrams. Vectors : NJC vectors questions are notoriously abstract,
Vectors: Intersection of planes, finding acute angles between surfaces, and properties of skew vs. parallel lines.
