A common mistake the examiners point out: No working shown: bare GDC answers and calculator notation. What to do instead: Write the formula or distribution first (X ~ B(n, p), P(X ≤ 3) = …), then the unrounded value, then the rounded answer. Convert calculator E-notation to a × 10ⁿ. Cross out the attempt you do not want marked.
