Unit 3
Construct and interpret time-series plots, identifying trend, seasonality, and outliers in 10 data sets
Calculate and interpret seasonal indices, then deseasonalise data and forecast with a trend line

Summarise Unit 3 in a two-page revision card using only headings and worked examples
Your checkpoint
Two completed timed papers with a written error analysis listing each mistake and its correct method
Unit 4
Build a Unit 4 formula sheet covering sequences, series, and recurrence relations from memory
Generate arithmetic and geometric sequences, and solve for terms, common difference, and common ratio in 20 problems
Apply recurrence relations of the form t(n+1) = a*t(n) + b to model growth and decay situations
Compute sums of arithmetic and geometric series and interpret them in context
Your checkpoint

Unit 3 & Unit 4
Complete two full-length mixed practice papers spanning both units under timed conditions
Re-solve every incorrect response from weeks 1 to 6 and confirm each method from scratch
Practise exam technique: allocate time per question, show required working, and check units and rounding
Compile a personal error list of recurring mistakes and the rule that prevents each one
Your checkpoint
Two timed mixed papers with a consolidated error list and corrected solutions for every error
Unit 3 & Unit 4
Review both revision cards and formula sheets daily, reciting key formulas from memory
