Cameroon GCE O-Level Mathematics study plan

Diagnose current ability by working through a full past-paper Section A under timed conditions and log every error by topic.

Re-learn and drill number bases: convert between base 10 and bases 2, 5 and 8, and perform addition and multiplication in another base.

Master directed numbers, order of operations and laws of indices, writing out each step without a calculator.

Build a personal formula sheet covering indices, standard form and surds, and commit the first ten entries to memory.

Solve problems on fractions, decimals, percentages and their interconversions, including percentage profit, loss and simple interest.

Apply ratio and proportion to sharing quantities and scale-drawing problems, showing unitary-method working.

Compute rates, average speed and density, and convert between units of length, mass and capacity.

Use standard form confidently for very large and very small numbers, including multiplication and division.

Simplify, add, subtract, multiply and divide algebraic fractions, stating restrictions on the variable.

Expand and factorise expressions including difference of two squares and simple quadratic trinomials.

Solve linear equations and simultaneous linear equations by both elimination and substitution.

Change the subject of a formula involving squares, roots and fractions.

Solve quadratic equations by factorisation, completing the square and the formula, and sketch the corresponding parabola.

Solve linear inequalities and represent solution sets on a number line.

Interpret and solve word problems that translate into linear or quadratic equations.

Complete one full past paper under exam timing and mark it strictly against the published scheme.

Apply Pythagoras' theorem and the sine, cosine and tangent ratios to right-angled triangles in two and three dimensions.

Use the sine and cosine rules and the area formula for non-right-angled triangles.

Calculate angles of elevation and depression and bearings in practical contexts.

Compute lengths of arcs, areas of sectors and surface areas and volumes of prisms, cylinders and cones.

Construct and interpret frequency tables, bar charts, histograms and cumulative frequency curves.

Calculate mean, median, mode and range from raw and grouped data, including the estimated mean of grouped data.

Read and draw scatter graphs, describe correlation and draw a line of best fit.

Compute simple probabilities from equally likely outcomes and from two-way tables.

Perform transformations of points and shapes: translation by a vector, reflection in given lines, rotation about a point and enlargement by a scale factor.

Describe a single transformation that maps one shape onto another.

Work with coordinates, midpoints, gradients and equations of straight lines, including parallel and perpendicular lines.

Apply loci and simple constructions using ruler and compasses.

Complete two full past papers under strict timing, one in each half of the week.

Re-work every question missed across the whole plan and confirm each is now correct without notes.

Memorise the final formula sheet and rehearse calculator and non-calculator routines.

Plan exam-day logistics: equipment list, timing per section and a strategy for questions to skip and return to.
