Includes the essential rewrite-first techniques OCR expects on this topic (turning surds and reciprocals into powers, expanding brackets and splitting a fraction over a single-term denominator) so no product, quotient or chain rule is ever needed, finding gradients at a point, second derivatives, exact-value gradients using e and surds, and finding an unknown constant from a gradient condition. Features the OCR ‘show detailed reasoning’ style, the 3 significant figure and exact-answer conventions, and a key-facts reference box reminding students that OCR prints none of the basic differentiation table. Progressive difficulty from Easy to Challenging. Ideal for revision, homework and cover lessons.

A complete 40-question worked-solutions pack on Data Presentation and Interpretation for OCR A A-Level Mathematics A (H240), covering the whole of specification section 2.02. It works through interpreting single-variable diagrams (vertical line charts, stem-and-leaf, histograms with equal and unequal class widths, cumulative frequency curves and box-and-whisker plots), frequency density and the area-represents-frequency rule, scatter diagrams and correlation (including two distinct sub-populations and why correlation is not causation), the full set of averages and spreads (mean, median, mode, quartiles, percentiles, interquartile range, standard deviation and variance from lists, summary statistics and grouped tables), outliers using both the 1.5 times IQR rule and the 2 standard deviations rule, choosing and critiquing diagrams, and cleaning data with missing values and errors. Diagrams are drawn inline for every question that needs one. Every question is graded Easy, Standard or Challenging and every solution is fully broken down: one atomic step per line, a plain-English note on every line, and OCR mark-scheme codes (M, A, B) folded in on the real credit-earning steps. The pack matches OCR conventions exactly, including 3 significant figure accuracy, the standard-deviation formula quoted as printed on the exam paper, the detailed-reasoning instruction on a synoptic question, and calculation of regression-line equations left off-spec as OCR requires. Ideal for revision, homework, or ready-made teaching examples. 34 pages.
