Common Mistakes Students Make

Mistake 1: Using “terrible” in formal writing

Many students write “The results were terrible” in an essay or report. This sounds too emotional and informal. Instead, use “poor,” “negative,” or “unfavorable.”

Correct: “The results were poor.”

Mistake 2: Overusing “bad” in comparisons

Instead of saying “This is bad, but that is worse,” use “inferior” for the first item. Example: “This method is inferior to the standard approach.”

Mistake 3: Confusing “negative” with “bad” in all contexts

“Negative” is best for effects, feedback, or outcomes. Do not use it for quality of objects. For example, do not say “This is a negative phone.” Say “This is a poor-quality phone.”

Mistake 4: Using “awful” in professional emails

“Awful” is too strong and informal for work or school emails. Use “poor” or “unfavorable” instead.
