Per ETS, the most common error on Numeric Entry questions is
Atyping letters instead of numbers
Bexceeding the character limit of the input box
Canswering before reading the question
Dright magnitude with wrong sign or wrong unit
Answer & Solution
Correct answer: D. right magnitude with wrong sign or wrong unit
ETS warns to 'pay attention to signs (positive vs negative) and units'. The arithmetic is often right; the entry is wrong. A profit-vs-loss problem flips sign; a metres-vs-cm problem multiplies by 100. Either way, exact magnitude with wrong sign or unit is automatically marked incorrect.
