Read scales, categories and relationships accurately across tables, charts and graphs before selecting or comparing values.
How to prepare for the TARA
Learn the official question types, practise five-option reasoning without a calculator, and rehearse one 40-minute writing process that explains, counters and judges a proposition.
Core concepts
Concept 1
The official mathematical scope includes extracting information from graphs, charts and tables.
Exam cue: Read the title, axes, legend and units before using a value.
Concept 2
Labels, units, scales and totals determine how a visual representation must be interpreted.
Exam cue: Translate each visual feature into a quantity or relationship.
Concept 3
Information may need to be combined across two representations.
Exam cue: Check totals and proportions when matching charts or tables.
Risk pitfalls and guardrails
Reading a category label from the wrong row or series.
Guardrail: Do not import subject detail the task does not require or confuse a plausible result with one established by the supplied reasoning.
Ignoring a non-zero axis or changing scale.
Guardrail: Do not import subject detail the task does not require or confuse a plausible result with one established by the supplied reasoning.
Comparing visual size without calculating the underlying quantity.
Guardrail: Do not import subject detail the task does not require or confuse a plausible result with one established by the supplied reasoning.
Memory anchors
Labels Before Values
Read axes, headings, legend and units first.
Scale Check
Confirm intervals and whether the axis begins at zero.
Cross-Reference
Use shared categories to link tables and charts.
Part and Whole
Check whether a value is a count, proportion or percentage.
Visual Is Data
Translate shape or area into the represented quantity.
Sanity Total
Use totals and obvious bounds to test the extraction.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
Knowledge Check (after reading)
Short check-up to confirm understanding of this module.
