Data Interpretation — Frequently Asked Questions
What actually makes DI sets slow?
Calculation, not comprehension. The data is simple; the marks go to whoever computes percentages and ratios fastest — which is why percentage fluency is a prerequisite.
Should I attempt every question in a DI set?
Usually one question per set is deliberately calculation-heavy. Attempt the direct ones first and return to the heavy one only if time permits.
