Hi,
Another practical and smart approach to ace maths is to
analyse deeply the concepts and skills which are often
assessed.
Look at some exam papers (Cambridge and school) and make
a checklist of concepts and skills. You may model the style I have
adopted for A-level maths:

Thanks!
P.S. If I may find time, I'll compile such a list for Additional
Mathematics later.
Cheers,

Hi,
Let me start a humble list (after referring to a school
exam paper) which could be improved upon by other visitors with
more detailed input.
1. Trigonometry
- Prove identities.
- Solve equations (sometimes after proving an
identity).
- Find min/max of an expression using the R-sine or
R-cosine result.
- Find values of trigonometric expressions, given
trigonometric ratios.
- Sketch trigonometric graphs (directly or after some
transformations) and show appreciation of period and
amplitude.
- Transformations include these forms: y = f(ax), y = f(x) +
a, y = |f(x)| and combinations.
- Determine the number of roots of given equations, where
their graphs need to be sketched and checked for the number of
intersections.
- Find trigonometric ratios of
specific angles without using calculator.
- Know about radian and degree
modes.
2. Surds and indices
- Form expressions using surds.
- Rationalise surds.
- Solve equations involving indices.
3. Logarithmic and exponential
functions
- Solve logarithmic equations.
- Solve real-life problems involving exponential functions
(e.g. radioactive decay of a substance).
- Simplify and evaluate,
without using calculator, using laws of logarithm.
- Sketch logarithmic and
exponential curves.
4. Modulus functions
- Sketch graphs of modulus functions.
- Solve equations and/or inequalities (by graphical
approach) involving modulus functions.
5. Circles
- Find equations of circles and show appreciation of radius
and centre.
- Find new equations given some transformation (e.g.
reflected about x-axis).
6. Quadratic equations
- Appreciate the nature of roots (real, equal, imaginary)
for graphs which are always above/below the x-axis, for graphs that
do not intersect, for graphs that are tangent to each other and the
like.
- Form new quadratic equations via sum and product of
roots.
- Solve quadratic
inequalities.
7. Binomial expansion
- Expand.
- Find terms independent of x or terms with certain
powers.
- Approximate values by suitable substitutions.
- Know how to expand nCr where
n is an unknown.
8. Linearisation of non-linear
expressions
- Express a non-linear equation by manipulation
to become Y = mX + c.
- Find slopes and intercepts in order to find unknowns in
the original non-linear form.
- Find values from graphs.
- Interpretations of linear
graphs.
- Draw another graph to find
the number of roots of an equation.
Part 2 coming soon...
Thanks!

P.S. I have added a few more points (in red) from my teacher
friend.
