Math tips
General
• Read questions properly!
• Check your answers.
• Don't dwell on questions.
• Know properties of shapes.
• Know your theorems.
• Be concise : Geometry with parallel triangles!
• Previous question lead on. E.g question 2 will help you answer question 3 .Remember
Hence.
• Equate graph e.g. y = X
• Put units/signs properly - degree sign on angle.
• Remember double angles.
• Know restrictions like if something cannot be negative - e.g years.
• If I made a mistake, redo the whole question.
• When it is said to be true when it is not necessarily true, say it is false.
• Know what section they are testing you on.
• Use formulas to aid in explaining.
• Accuracy : If not exactly on line, then it is greater. E.g say 121 not 120.
Algebra
Restrictions
• Know restrictions such as for square roots.
• For x =y, it must reflect. Swop x and y - for everything.
E.g for inverse restricted functions of x =y, if x > 0 then y > 0.
Probability
Say the discrepancy can be ignored.
Analytical geometry and Geometry
• Use vert opp
• Use congruency, similarity & opp ang equal.
• A tangent is perpendicular to the diameter.
Know your properties of shapes.
For rhombus, the diagonal lines are not equal.
A kite two pairs of consecutive sides are =
Theorems
For the Tan chord theorem, the angle between the line and chord is equal to the angle
subtended by the chord in the alternate segment.
