O level Elementary Paper 2 possible topics to be tested
1.
Algebra (subject of formula, algebraic
fractions, simultaneous equation, linear inequality, indices equation, special
products, complete the square)
2.
Finance (percentage, compound interest,
hire purchase, commission, foreign exchange, standard form)
3.
Number
Pattern
4.
Coordinate
Geometry (length
formula, gradient, simultaneous equation to find intersection points, find
coordinates of parallelogram, trapezium, trigonometric ratio of obtuse angle)
5.
Properties
of Circle (may
have parallel lines making use of interior angles, alternate angles and
corresponding angles, may have congruency proving)
6.
Arc
length and sector area
(may appear together in one question with properties of circles)
7.
Mensuration (pyramid, prism, sphere, cone,
cylinder, 3D diagram, area of polygon, may use TOA CAH SOH, similarity ratios,
angle of elevation or depression)
8.
Trigonometry (cosine rule, bearings, angle of
elevation and depression)
9.
Congruency
proving, may
involve parallel lines and ratio of area of triangles
10.
Quadratic
Equations: to prove
to ax^2+bx+c , could be rates or mensuration question.
11.
Cumulative
Frequency curve:
could be those that need tabulation of values from cumulative frequency table into
grouped frequency table to find SD and mean, make comparison and find
probability. Box and whisker plot, stem-and-leaf, dot diagram possible
12.
Probability: Tree diagram, possibility diagram
13.
Real
World Question
(mensuration: may involve cylinder, sector area and arc length, angle bisector
and perpendicular bisector, map scale, bearings, statistics, probability,
angles)
