Variable Definitions

One variable per line. Syntax:
name: range(min,max)
name: range(min,max,step)
name: range(min,max,step,distinct) — differs from other distinct vars
name: set(a,b,c,…)
name: expr(formula)
Use {name} in templates. Append :2dp for decimals: {x:2dp}

Question Template Formula *

Use {varName} for variable substitution.

Answer Template *

Use the same variable names for the computed answer. Leave blank for Multiple Choice — the answer is derived from the correct option.

Answer Generation Formula (optional)

A raw expression evaluated after variables resolve, stored as {ans_final}. Use when the answer needs computing, e.g. (p/100)*n.

Marking Scheme Generation Formula

One step per line. Append (1 mark) or (2 marks). Step marks are auto-summed and checked against Marks Allocation.
