Possible topics to be tested for 2015 O'Level Elementary Maths Paper 2

Hi all,

Here are the possible topics for tomorrow's 2015 O'level Elementary Maths paper 2:

1. Number patterns( may test indices)
2. Proving of similarity & congruency
3. Properties of circle (may mixed with similarity)
4. Vectors in the form of a and b (may mixed with similarity)
5. Prove quadratic equation and solve (may mixed with mensuration eg trapezium parallelogram n circles, speed)
6. Hire purchase/compound and simple interest
7. Taxation, foreign exchange, utilities
8. Graph drawing, explaining what tangent represent. use intersection to solve eqn, simultaneous eqn
9. Algebra: combine as single fraction, complete the square, simultaneous eqn (may be problem sum format), standard form qn, map scale, inverse and direct proportion
10. Trigo: angle of elevation/ depression, area, 3d diagram eg pyramid, toa cah soh
11. Cordinate geometry: distance formula, y=mx+c, gradient, simultaneous with quadratic curve, find x and y intercepts
12. Mensuration, sphere, pyramid, cone, cylinder, prism, test volume
13. Cumulative freq curve, median, interquartile range, histogram, box-and-whiskers, stem & leaf and dot diagrams
14. Kinematics (speed, distance acceleration)
15. Sketching of graphs (power functions and exponential)

All the best to all students who are taking the examinations tomorrow!
