QR Data Formats You Must Recognise Instantly
Speed in QR comes from recognising the data format in under 5 seconds and knowing exactly which part of it to read. Practise with every format until identification is automatic.
- โTables: scan column headers first; ignore columns that are irrelevant to the question
- โBar/line charts: read axis scales carefully โ mislabelled scales are a deliberate trap
- โPie charts: convert percentages to absolute numbers using the total given
- โCurrency and unit conversion: write the conversion factor before calculating to avoid errors
